While investigating suspected drug activity at a motel in Mattoon, Illinois, police detained convicted-felon Shawn Adamson and discovered a .22 caliber handgun in his possession. Mr. Adamson was charged with being a felon in possession of a firearm. See 18 U.S.C. § 922(g)(1). He moved to suppress the handgun as the product of an unreasonable search and detention. The district court denied his motion. Adamson then pleaded guilty and was sentenced to 24 months’ imprisonment. On appeal, he challenges the district court’s denial of his motion to suppress. For the reasons set forth in the following opinion, we affirm the judgment of the district court.

BACKGROUND
A. Facts
The facts pertaining to this appeal arise out of a routine home visit conducted by probation officers of a probationer’s motel room at Hannah’s Inn in Mattoon, Illinois. In the room, the officers discovered drug residue and paraphernalia and noticed several individuals hastily leaving the motel *516 through a back exit. Together with local police, the officers began questioning these individuals. In this group was Adamson, who, when police found him, was clutching what appeared to be a bundle of clothing. A pat-down search of Adamson and his parcel revealed a handgun wrapped in a pillowcase. At the hearing on Adamson’s motion to suppress, the district court heаrd testimony from the police officers involved in the encounter with Adamson and from several witnesses called by the defense. The testimony conflicted. We first shall set forth the story presented by the officers and then describe the account of the defense witnesses.
1. The Officers’ Testimony
At the suppression hearing, probation officer Steve Kelly, Mattoon police officers Brad Gabel and Jeremy Clark and Auxiliary Sergeant Steve Newlin testified for the Government. Kelly testified that he went to Hannah’s Inn with a few other probation officers to conduct a home visit for a probationer who resided there. The officers also were looking for a second probationer, who was the subject of an outstanding warrant. The probation officers first spoke with a motel employee who told them that the second probationer was staying in the motel and was currently in a rоom with four other people: “two black males and a couple white individuals.” R.45 at 8, 10. The probation officers went to that room, where they found drug residue and paraphernalia. The probationer, who was the subject of the home visit, was alone in the room. He admitted that, just prior to the officers’ arrival, he had been using drugs with some other individuals, but he declined to identify them.
Kelly, hoping to find the probationer with the outstanding warrant, then left the motel room in search of the others. He observed four individuals — two black men, a white man and a white woman — leaving the motel through a back exit “the minute” he stepped outside the motel. Kelly recognized two of the men, Adamson and Darryl Ferrell, as former probationers. The officer had been involved in “a violent incident” with Ferrell in the probation office on a previous occasion and had participаted in a home visit when Adamson was a juvenile probationer. Kelly knew that both men had prior felony convictions.
As he approached the four individuals, Kelly noticed that Adamson was clutching what appeared to be a white bag, as well as some clothing, “very tightly in front of his chest and ... seemed to wrap around it and be very concerned.” Id. at 12. Kelly testified that he knew from “community reports” that Adamson “was known to be carrying and at timеs brandishing a firearm.” Id. at 13. Kelly asked the two individuals that he did not recognize for identification; they refused. He then asked all four individuals if they were motel residents, and one of them replied affirmatively. Kelly stated that Adamson “was acting a little bit differently than my prior encounters with him,” id. at 15-16; instead of acting “very argumentative, profane, basically telling me where to go,” id., he was nervous. Kelly radioed the Mattoon Police Department and asked the dispatcher to send a squad car. He asked Adamson and his companions to “stand by until we could sort through the situation with the crime scene in the room.” Id. at 17. Kelly testified that there was “no objection whatsoever” and that all four individuals followed his request. Id.
About ten minutes later, Officer Gabel arrived at the motel. Kelly told Gabel that, based on his past experience with Adamson and Adamson’s behavior that day, he was “very suspicious” that Adam-son might be armed. Immediately, Gabel recognized Adamson from prior encoun *517 ters and knew that he was a convicted felon. After the probation officers apprised him of the situation, Gabel obtained identification from each of the four and contacted the police dispatcher to check for outstanding warrants. Adamson told Gabel that he did not have any drugs or weapons on his person, but that Gabel could nоt “check him.”
Within ten minutes, Officer Clark and Sergeant Newlin arrived on the scene. Shortly after their arrival, “someone mentioned that there was a possibility of a weapon from a report that happened the night before.” Id. at 19. Clark asked Adamson whether he minded if Clark searched him for weapons and, according to Clark’s testimony, Adamson replied, “Whatever.” Clark then asked Adamson to put down the bundle he was carrying, and Adamson rested it in the bed of a pickup truck. After Adamson placed his hands on the side of the truck, Clark patted him down. Meanwhile, Kelly reached into the truck bed and ran his hand along the top of Adamson’s bundle “to see if [he] could possibly feel the outline of a weapon inside the belongings.” Id. at 20. When he ran his hand over the pillowcase, Kelly “immediately” felt the outline of a gun. Kelly told Newlin what he felt; Newlin also felt the pillowcase and verified that there appeared to be a gun inside. Newlin then informed Clark and Gabel that he and Kelly had felt a handgun in the bundle of clothing that Adamson had been carrying. At that time, Gabel handcuffed Adamson and formally arrested him for possession of a firearm by a felon. Once Adamson was in custody, Gabel and Clark “went through the clothing and removed the gun.” Id. at 43.
2. The Defense Witnesses’ Testimony
Mr. Adamson called two witnesses at the suppression hearing. First, Darryl Ferrell testified that he had spent thе day of February 19 with Adamson and “a couple more people” drinking and playing video games in a friend’s room at Hannah’s Inn. They left when alerted to the presence of probation officers at the motel. As the group left through a rear exit, they were approached by Officer Kelly, who began to ask them questions. When Officer Gabel arrived on the scene, Ferrell testified, Adamson refused to be searched becаuse he “wasn’t on probation” and “didn’t have any arrest warrants.” Id. at 75. According to Ferrell, the two other individuals did consent to being searched. After Clark and Newlin had arrived on the scene, one of them “asked everybody” to be searched, and Adamson again refused, stating that he was not on probation and did not have any outstanding warrants. Ferrell testified that Adamson was handcuffed and arrested before any of the officers pattеd him down. He further stated that Adamson did not have a gun with him that day and that he never saw the police recover any weapons from anyone on the scene. On cross-examination, Ferrell admitted that he previously had been convicted of aggravated battery against probation officer Kelly. Ferrell also admitted that he was drinking alcohol for several hours before the officers arrived at Hannah’s Inn.
Shelby Guyette, the wоman in Adam-son’s group that day, testified that she had been pulled aside by one of the probation officers and that “whenever I came back, they were searching [Adamson].” Id. at 91. She stated that Adamson refused to be searched but was told to set down his bundle of clothing and was searched anyway. After the officers searched Adamson and the clothing, Guyette testified, they placed him in handcuffs and arrested him. Guyette did not recall who searched Adamson or whether it was a police officer or probation officer.
*518 B. District Court Proceedings
After receiving closing arguments in written form, the district court denied Adamson’s suppression motion. The district court found that Kelly, Gabel, Clark and Newlin were credible witnesses but that Ferrell and Guyette were not; the court contrasted Ferrell and Guyette’s testimony with the “straightforward” and “consistent” testimony of the officers. In addition, Ferrell had admitted to consuming alcohol on the day of the incident, and he had a prior conviction for aggravated battery in connection with an altercation with Kelly. The district court doubted the credibility of Guyette’s testimony and her “ability to observe” because she had testified that she did not observe any evidence of drinking in the motel room despite Ferrell’s admission that he had been drinking for several hours that day. The district court also cited the witnesses’ “mannеr and demeanor” as reasons for discrediting Ferrell and Guyette.
The district court first concluded, based on Kelly’s credible testimony, that Adam-son had consented to wait in the parking lot with Kelly until police arrived. In the alternative, the court held that there was reasonable suspicion to believe that Adam-son was involved in criminal activity because of Kelly’s familiarity with Adamson and the motel employee’s description of the individuals who had been in the room where probation officers discovered drugs and drug paraphernalia. Next, the court found that Adamson had consented to be searched when he answered, “Whatever” to Clark’s request. The district court also concluded, in the alternative, that the officers had reasonable suspicion to pat down Adamson and the bundle he was carrying. The court cited Adamson’s proximity to the motel room where drugs were discovered, the police report that he had brandished a gun the day before, his nervous demeanor and the fact that he seemed to be guarding his pile of clothing. The court noted that it would “defy logic” to conclude that the officers had reasonable suspicion to pat down Adamson’s person but not the bundle he was clutching. The court denied Adamson’s motion, and weeks later he pleaded guilty, reserving the right to сhallenge the denial of the suppression motion.

DISCUSSION
When evaluating the denial of a suppression motion, we review questions of law de novo and findings of fact for clear error.
See United States v. Banks,
A.
Before addressing the contentions set forth in Mr. Adamson’s oрening-brief, we must pause to note that, in that brief, he leaves unchallenged the explicit factual findings that he consented to remain with Kelly and to undergo the subsequent pat-down search. To the extent that Adamson mentions the district court’s finding of consent at all, he baldly asserts that he was stopped and searched without
*519
consent. He does not contend, however, that the district court clearly erred in finding that he acceded to Kelly’s request to “stand by” until police arrived and that he answered, “Whatever” in response to Clark’s request for consent to search him for weapons. These findings stem from the district court’s decision to credit the testimony of Kelly, Clark and Newlin over that of Ferrell. Credibility determinations are factual in nature and therefore are reviewed for clear error; a credibility determination will be found clearly erroneous “only if the district сourt has ‘chosen to credit exceedingly improbable testimony.’ ”
United States v. Robinson,
In failing to challenge the district court’s factual findings that he consented to wait with Kelly and to be patted down by Clark, Adamson also passes over any argument with respect to the scope of his consent. The district court found that Adamson consented to remain in the motel parking lot “until police arrived.” R.16 at 5. The Government interprets this finding to mеan that Adamson consented to stay on the scene “while officers conducted a drug investigation.” Appellee’s Br. at 16. Even after learning the Government’s view that his consent extended to the entire encounter — not merely until the arrival of police — Adamson in his reply brief declines to respond to the Government’s expansive interpretation or to its submission that the duration of the encounter is irrelevant because it was сonsensual. He does not suggest that his consent was limited in scope or was withdrawn at any point, although he does hint that his consent, if given, was not “voluntary.” For its part, the Government states that the district court “found that the defendant consented to a pat-down search for weapons that included the pillowcase he was carrying.” Id. at 37. With respect to the search, the district court found that Adamson “consented to a pat down sеarch.” R.16 at 6. Again, Adamson does not dispute the Government’s understanding of the finding of consent or assert that his consent did not extend to his parcel.
In light of Adamson’s failure to challenge the district court’s factual conclusions, and the “near absolute deference” owed to the district court’s credibility determination,
see United States v. Williams,
B.
We now shall address the district court’s alternative holding that the stop and pat-down search were independently justified by reasonable suspicion.
Mr. Adamson first contends that he was stopped initially without reasonable suspicion. We believe that it is clear that his initial interaction with Kelly was not a seizure that implicates the Fourth Amendment.

It is well settled that police may
*520
approach an individual in a public place and seek the individuars cooperation in answering a few questions. Such an encounter is not a “seizure” within the meaning of the Fourth Amendment.
See United States v. Broomfield,
However, the encounter soon ripened into an investigative detention.
See Terry v. Ohio,
Mr. Adamson also contends that, even if there was reasonable suspicion for a
Terry
stop, the duration of the stop eventually rendered it a de facto arrest, requiring probable cause.
See Robinson,
*521
With respect to the discovery of the gun, the manipulation of a person’s effects from the outside is a “search” within the meaning of the Fourth Amendment.
Bond v. United States,
The elapsed time is the only evidence Adamson cites in support of his position that the officers were not concerned with their safety at the time of the search. This argument addresses whether the officers, having not immediately patted him down, subjectively believed that he was armed. But reasonable suspicion is measured against the totality of the circumstances, and the test is objective.
See Ford,
Conclusion
The district court did not clearly err in finding that Adamson consented to the initial stop and to the pat-down search. Furthermore, the officers had reasonable suspicion that Adamson was involved in criminal activity and that he posed a threat to officer safety. Accordingly, the judgment of the district court is affirmed.
AFFIRMED.
Notes
. Although Kelly is a probation officer rather than a police officer, the Fоurth Amendment
*520
applies to governmental actors other than police officers, such as probation officers.
See New Jersey v. T.L.O.,
. Mr. Adamson suggests for the first time in his reply brief that officers lacked reasonable suspicion to pat down the pillowcase because he was not holding it and could not access its contents at the time of the pat-down. Arguments made for the first time in a reply brief are waived,
