Defendant Tavon Robinson was convicted of conspiracy to possess with intent to distribute and to distribute cocaine, 21 U.S.C. § 846; possession with intent to distribute and distribution of cocaine, 21 U.S.C. § 841(a)(1); being a felon in possession of a firearm, 18 U.S.C. § 922(g)(1); and possessing a firearm in furtherance of a drug trafficking offense, 18 U.S.C. § 924(c)(1)(A).
Robinson appeals both firearms convictions and his sentence, alleging prosecuto-rial misconduct, insufficient evidence, and improper sentencing. We AFFIRM.
I.
In 2004, DEA Special Agent David DiTullio agreed to purchase two ounces of crack cocaine for $2,350 from Adam Ellard as part of an undеrcover drug investigation. Unable to locate any crack cocaine for the deal, Ellard contacted Willie Hester, whom he had seen packaging crack on a previous occasion with another man, Norman Barnes. Hester agreed to sell Ellard sixty-two grams of crack cocaine, but conditioned the sale on his accompanying Ellard to the deal.
Hester picked up Ellard in a Honda, followed by a Ford 1 with New Hampshire plates. The Ford had three occupants: Robinson in the driver’s seat, Stephen Tucker in the front passenger seat, and Barnes in the back. The two cars traveled to a parking lot in Dorchester tо complete *392 the deal with DiTullio. Ellard exited the Honda and entered the passenger side of DiTullio’s vehicle. He told DiTullio that the crack cocaine was in the Ford and requested the $2,350. DiTullio showed El-lard the money, let him count it, but would not give it to him unless he produced the crack cocaine. Ellard returned to the Honda to consult with Hester, who told him to go speak with Barnes in the Ford. Barnes informed Ellard he would not produce the drugs without any money. In an attempt to compromise, Ellard had DiTul-lio back his vehicle up to the rear of the Ford. DiTullio again refused to give Ellard the money without the drugs.
Frustrated аt the stalled deal, Robinson exited the driver’s seat of the Ford, walked to the front of the hood for a few moments, 2 and then proceeded to DiTul-lio’s vehicle. Speaking with DiTullio through the passenger window, Robinson removed a clear plastic bag 3 from his jacket pocket and placed it on the front passenger seat. DiTullio gave Robinson the money, and Robinson began walking back to the Ford. As law enforcement officers moved in for an arrest, Robinson fled briefly before being apprehended. He was arrested and police found $2,350 and a clear plastic bag containing marijuаna and crack cocaine in his possession.
After seizure of the Ford, an inspection at a garage revealed two loaded semiautomatic pistols wrapped in a T-shirt and hidden inside a small space in front of the engine compartment near the front of the hood. 4
The next day, Officer Conners overheard Robinson and Barnes conversing in their shared holding cell. According to Officer Conners, Robinson remarked to Barnes, “It’s not crack anyway. It’s only coke. They’ll find that out when they do the lab tests.” Officer Conners also heard Robinson tell Barnes that “When they came from everywhere, I сould have gone boom, boom.”
At trial, in his opening statement, Robinson’s counsel admitted his client’s guilt on the drug charges, 5 but argued that he was unaware of the firearms’ presence. Robinson was convicted on both firearms charges. The district court denied Robinson’s motion for judgment of acquittal and sentenced him to 137 months. 6

de novo. United States v. Hall,
III.
Robinson raises three issues on appeal: prosecutorial misconduct, insufficient evidence, and improper sentencing. We address each issue in turn.
A.
Robinson’s first argument is that the prosecution repeatedly engaged in a pattern of misconduct during both cross-examination and closing argument when it systematically portrayed him as a habitual drug user and career drug dealer. He contends that the government’s questions about the drug deal with DiTullio and repeated questions and references to his pri- or history of drug trafficking constitute reversible error because they confused the jury into convicting him on the gun charges based mostly on his prior history of drug trafficking.
Robinson argues that the government improperly elicited prejudicial testimony regarding the drug deal with DiTullio. According to Robinson, such testimony was unnecessary because he never challenged his guilt: defense counsel informed the government prior to trial that he would not deny his role in the drug deal with DiTullio, defense counsel’s opening statement conceded his guilt to the drug trafficking charges, at no time during the trial did he otherwise contest his guilt, and on the morning of the third day he entered guilty pleas to both drug charges. Thus, he argues, the government was relieved of its burden to prove that Robinson engaged in drug trafficking as part оf its charge that he possessed a firearm in furtherance of a drug trafficking offense. Robinson contends that the sole reason the government focused on this drug deal was to make the jury believe it was to convict him for his drug trafficking activities and not the firearms charges.
This argument is unavailing for several reasons. First, although he conceded his role in the drug deal with DiTullio prior to trial and during his opening statement, Robinson remained free to change his mind whether he would contest both drug trafficking charges at some point in the trial. He did not formally enter guilty pleas to both charges until the morning of the third day of trial, and until that time the government still had the burden to prove his guilt beyond a reasonable doubt. Therefore, it was proper to present evi *394 dence that Robinson engaged in drag trafficking.
Robinson claims the government also engaged in misconduct when it repeatedly questioned him about his prior drag use and involvement in drug trafficking during his cross-examination and when it returned to this theme in closing arguments. He argues that these questions and closing statements constitute misconduct and violate Fed.R.Evid. 404(b).
On several occasions during Robinson’s cross-examination, the government attempted to question him about his history in dealing and using drugs. 7 At a sidebar after repeated defense objеctions, the government told the district court that it was not inquiring about prior bad acts, but rather showing that Robinson knew about the dangers of dealing drags in order to prove the “in furtherance” element of possessing a firearm in furtherance of a drug trafficking offense. Several times after the sidebar, the government again attempted to ask Robinson about his drug-dealing history in an effort to prove why he would bring a gun to a drag deal and how he knew prices of drugs.
Evidence of “a defendant’s other bad acts [is proper] only if that evidence meets the requirements of both Rule 404(b) and Rule 403.”
United States v. Tse,
Robinson claims that the mere asking of these questions was prejudicial.
See United States v. Meserve,
In response to a question asked without objection, Robinson admitted that it was not out of the ordinary for him to be selling drags. Moreover, on the third day of the trial, Robinson pled guilty to the two drug charges. At this point, the jury had heard considerable evidence regarding Robinson’s drag deal with DiTullio. Therefore, it is difficult to see how the questions prejudiced Robinson.
Robinson cites to two main cases to support his contention that reversal is required. However, these cases are distinguishable. First, he cites
United States v. Crawford,
Robinson similarly cites to
United States v. Newman,
Robinson next claims the prosecution committed reversible error when it asked him on cross-examination whether two law enfоrcement witnesses lied on the witness stand. Agent Genese had testified that when he asked Robinson whether he knew the cocaine he sold to DiTullio was real or fake, Robinson responded that he did not know. During Robinson’s cross-examination, he denied saying that he was unsure what he sold. The prosecution then asked him if Agent Genese was lying. 9
At another point, Officer Conners testified that he heard Robinson state that when the officers surrounded him just pri- or to his arrest, he could have gone “boom, boom.” During Robinson’s cross-examination, he denied making the statement and responded that Officer Conners could have been mistaken. The government then asked Robinson if Conners was lying, to which he answered that he did not know and was unable to say. 10
“This Court has held it is improper for an attorney to ask a witness whether another witness lied on the stand.”
United States v. Thiongo,
Because Robinson objected to the government’s question asking whether Agent Genese wаs lying, it is reviewed for harmless error.
See United States v. Sullivan,
*396
Robinson did not object when the government asked him if Officer Connors was lying. Therefore, we review this question for plain error.
11
See Fernandez,
Robinson also argues that the government continued to impermissibly vouch for the law enforcement officers in its closing argument. In relevant part, the prosecutor argued:
Ladies and gentleman, if you believe that the officers of the United States, if you believe that these agents got on that stand with all those years of experience and in the face of their oath stood up there and lied in their testimony and you believe they did that, then acquit the defendant. Then acquit the defendant.
Because there was no contеmporaneous objection, we review for plain error.
United States v. Wilkerson,
411 F.3d I, 7 (1st Cir.2005). Improper vouching occurs when the government “placets] the prestige of the United States behind a witness by making personal assurances about the credibility of a witness,”
United States v. Rosario-Diaz,
The government’s statement merely invited the jurors to acquit Robinson if they believed that Agent Genese and Officer Conners were lying. This is not the type of improper vouching prеsent in
Rosario-Diaz
or
Perez-Ruiz
because the government neither made statements about the witnesses’ credibility nor implied that they could be trusted based on their affiliation with the United States. Moreover, these statements do not rise to the level of plain error.
See Wilkerson,
In addition to arguing that the government improperly vouched for law enfоrcement witnesses in its closing argument, Robinson alleges other instances of prejudice in the government’s summation. Because he failed to object to the government’s closing argument, we review for plain error.
Sullivan,
Robinson claims that the government’s first statement in its closing argument directed the jury to convict him based on his alleged life of crime rather than his alleged possession of firearms. 13
While “arguments urging a jury to act in any capacity other than as the impartial arbiter of the facts in the case before it are improper,”
United States v. Manning,
Robinson next alleges that the government’s closing argument impermissibly returned to his history as a drug dealer. Robinson’s brief selectively excerpts sentences from the government’s summation and dissects each sentence to arrive at his conclusion that the closing was plain error. However, we must view the context of the remarks in determining whether error exists. Id. Viewed accordingly, these remarks are not plain error. The government’s closing argument focused on the uncertаinty surrounding the drug deal and the notion that drug dealers, including Robinson, bring guns to drug deals to protect themselves. The government merely repeated what Robinson admitted to, without objection, on cross-examination: that he knew the “ways of the world” and about drug deals in general.
The closest the government came to impermissibly prejudicing the jury in its closing argument was when it concluded its rebuttal:
I would suggest to you, ladies and gentlemen ... that [Robinson is] guilty of possessing those guns in furtherance of that drug deal in which anything could have happened and probably something would have happened had it been a real drug dealer and not a DEA undercover agent who was getting ripped off by the defendant.
While it is improper to “needlessly arouse the emotions of the jury,”
United States v. Pirovolos,
*398 Robinson argues that even if any of the alleged prosecutorial errors do not, by themselves, require reversal, the totality of the government’s misconduct compels the conclusion that Robinson was denied a fair trial. We do not accept Robinson’s premise that every evidentiary error in a criminal trial amounts to government misconduct. Nevertheless, for ease, we will use the misconduct test to address his arguments.
We weigh several factors in determining “whether prosecutorial misconduct has so poisoned the well that a new trial is required: (1) the severity of the misconduct; (2) the context in which it occurred; (3) whether thе judge gave any curative instructions and the likely effect of such instructions; and (4) the strength of the evidence against the defendant.”
United States v. Casas,
First, the government’s conduct was not as severe as Robinson alleges. While some of the prosecutor’s questions regarding Robinson’s history of drag dealing may have been improper, their sole purpose, unlike in Neivman, was not to paint Robinson as an evil character, but to show his motivation for carrying a firearm to a drug deal. The government also appeаled to the jury’s emotions in closing, perhaps needlessly, but considering the context of the entire closing argument and rebuttal, the statements were not highly prejudicial.
Second, we should look at the time when the alleged misconduct occurred. The government properly elicited testimony about the drug deal with DiTullio because at the time it asked those questions, Robinson had not yet formally pled guilty to those charges. Once Robinson entered a formal guilty plea, the government shifted its focus from the drug deal to the gun possession. Therefore, the government did not cause the jury to be unnecessarily focused on the drug charges and the questions did not heighten prejudice or create confusion as Robinson suggests.
Third, while the district court gave no curative instructions, Robinson requested none. The district court did give general instructions before deliberations regarding what the jury could and could not consider as evidence, including questions with sustained objections, opening statements, and closing arguments.
Finally, evidence of Robinson’s guilt was neither exceptionally weak nor exceptionally strong. The government introduced sufficient evidence to convict Robinson on the firearms charges, but this evidence did require a finding of constructive possession.
Taking these factors together, Robinson was not sufficiently prejudiced to entitle him to a new trial. The underlying fairness of the trial was not compromised because, although there may have been error, it was not sufficiently linked to the outcome so as to require a new trial.
B.
Robinson next argues that the government failed to produce sufficient evidence at trial to prove that he knowingly possessed a firearm in furtherance of a drag trafficking crime. He contends that the evidence indicates that he had no role in hiding the guns or was even aware of their existence.
In order to prove possession of a firearm, the government must show actual possession or constructive possession. Constructive possession “exists when a
*399
person knowingly has the power and intention at a given time to exercise dominion or control over the area where the contraband is found.”
United States v. McLean,
The evidence was sufficient to permit a rational jury to conclude that Robinson constructively possessed the firearms found in the engine compartment. First, even though the evidence showed that Robinson neither rented the Ford in which the firearms were found, nor owned the firearms,
14
constructive possession does not require ownership of either the guns or the area in which they are located. All that is necessary is that the defendant knowingly have the ability and intent to exercise dominion and control of the firearm or area where it is located.
See United States v. Carpenter,
A rational jury could have concluded that Robinson had the ability and intent to exercise dominion and control of the firearms for several reasons. Even though the Ford was rented to Mercer, Robinson’s relationship with Tucker provided him with ample opportunity to store the guns in the engine compartment. Evidence was presented that Robinson and Tucker were friends, that Mercer left the keys to the Ford in various locations around the house where Tucker and Robinson would have easy access to them, and thаt Robinson was part of a group who was to drive the Ford to New Jersey for a trip.
Second, a rational jury could have interpreted Robinson’s statement to Barnes in the holding cell that “When they came from everywhere, I could have gone boom, boom,” to mean that Robinson could have shot the agents using the firearms found in the Ford.
Robinson contends that even if the evidence was sufficient to prove that he knowingly possessed firearms, there was insufficient evidence to prove that he possessed the firearms in furtherance of a drug trafficking offense.
Under 18 U.S.C. § 924(c), the government must prove that the firearm was possessed “to advance or promote the commission of the underlying offense. The mere presence of a firearm in an area where a criminal act occurs is not a sufficient basis for imposing [the] mandatory sentence [under § 924(c) ].”
United States v. Grace,
Here, the jury had ample reason to conclude that Robinson possessed the firearms in furtherance of the drug deal with DiTullio. Both firearms hidden in the Ford were loaded and were accessible by Robinson during the drug deal with DiTullio. All Robinson had to do to gain actual possession of the firearms was to open the Ford’s hood three to six inches and reach inside the engine compartment. Moreover, because Robinson had the drugs on his person when he was inside the car and subsequently opened the hood, the firearms were within close proximity to the drugs. Also, a jury could have concluded that Robinson was in charge of the drug deal and that the firearms were available if necessary because Robinson drove the car and took charge when the drug deal appeared as if it would not happen. Therefore, sufficient evidence existed for the jury to find that Robinson рossessed the firearms in furtherance of a drug trafficking offense.
C.
Robinson’s final claim is that the district court erred at sentencing. He contends that “[t]he district court erroneously believed it was constrained by the United States Sentencing Guidelines (‘Guidelines’) when it sentenced” him to 137 months. Specifically, he points to the district court’s comment that “I think that — I don’t have a whole lot of discretion here. I — but I don’t see any reason to go to the high end of the advisory guideline range. I think 137 is the lowest I can do with the [60-]month consecutively-run sentence,” as evidence that the district court misapprehended its discretion under the Guidеlines.
Since
United States v. Booker,
Robinson’s claim fails for two reasons. First, the district court clearly understood
Booker’s
holding because it explicitly referred to the Guidelines range as “advisory” in determining Robinson’s sentence. Second, the district court’s statement regarding its apparent lack of discretion does not appear to refer to its inability to depart downward under the Guidelines because of their mandatory nature. Rather, that statement reflects the district court’s conclusion that after considering all relevant sentencing factors, it could not provide adequate reasoning for imposing a sentence below the advisory Guidelines range. In order to depart downward the district court would have been required to give an express or implied reason for doing so, and it felt it could not do so based on the evidence presented at sentencing. During Robinson’s sentencing, the district court remarked that it was troubled by Robinson’s belief that this case “was no big deal,” his inability to stay out of trouble at home, and his apparently fabricated testimony. Considering these statements in light of the record, see
Jimenez-Beltre,
IV.
For these reasons, we AFFIRM Robinson’s convictions and sentence.
Affirmed.
Notes
. The Ford was rented to Cleo Mercer, the sister of Stephen Tucker.
.Cоnflicting testimony was presented at trial regarding Robinson's conduct in exiting the car and moving to the front of the. hood. Ellard testified that Robinson unlatched the hood from inside, reached between the hood and the grill stating, "I'm looking for something,” but closed the hood without removing anything. DEA Group Supervisor Richard Guerard, who conducted surveillance of the transaction, testified that Robinson opened the hood "about five or six inches” and then closed it. DiTullio testified that Robinson opened the hood approximately one-quarter of the way, removed an item and put it in his jacket pocket. Agent Steven Stoiy, who also conducted surveillance, testified that Robinson opened the hood approximately eighteen inches, but shut it without removing anything.
. The parties stipulated at trial that the clear plastic bag contained 28.2 grams of crack cocaine.
. Agent Story testified that Robinson would have access to the space where the pistols were hidden with the hood partially open. Gloucester Police Officer Sean Conners also testified that the space was accessible if the hood was only open three to six inches.
. Robinson pled guilty to the drug charges on the morning of the third day of the trial.
. Robinson was sentenced to 77 months concurrently for the drug charges and being a felon in possession of a firearm. He was also sentenced to 60 months for possessing a firearm in furtherance of a drug trafficking offense.
. Robinson objected to some questions along this line, but not all.
. Because of Robinson’s inconsistent objections to this line of questioning, the plain error and harmless error standards apply to different questions. However, as discussed infra, Robinson cannot make a showing of prejudice under the lesser harmless error standard.
. Robinson objected to this question, which the court sustained.
. Robinson did not object to this question.
. The government’s question to Robinson whether Officer Conners was "mistaken” was proper.
See Gaines,
. In fact, Robinson’s brief seemingly concedes no inherent prejudice in this particular question. ("While these questions in isolation may not have been reversible error.... ”).
. The government’s closing argument began: "There comes a time in every man and woman's life that they must be held accountable for their actions. That time for this defendant, Tavon Robinson, is here and now.”
. Evidence showed that Tucker purchased one of the pistols from Daniel Clagon.
