OPINION
Betty Mitchell (the “Warden”) appeals from the district court’s order granting in part John Gillard’s petition for a writ of habeas corpus pursuant to 28 U.S.C. § 2254. Gillard, an Ohio prisoner under a death sentence, cross-appeals from the district court’s denial in part of his petition. The district court granted Gillard habeas relief on two issues: his trial counsel labored under a conflict of interest and the cumulation of errors at trial violated his constitutional rights. Because Gillard is not entitled to habeas relief, we REVERSE the district court’s order as to those two claims and AFFIRM as to all remaining claims.
I. BACKGROUND
In
State v. Gillard,
On December 31, 1984, Timothy Hendricks held a New Year’s Eve party in his home at 213 Kennet Court, N.W., Canton. Among the guests were Ronnie Postlethwaite, Denise Maxwell, Leroy Ensign, and defendant-appellee’s brother William Gillard. During the party, there was a fight between Ensign and Gillard. After Hendricks broke up the fight, William Gillard left.
The party ended between 3:00 and 4:00 a.m., January 1. Seven guests stayed the night, including Ensign, Postlethwaite and Maxwell.
Postlethwaite and Hendricks were both awakened by a gunshot outside. Hendricks went back to sleep. Postlethwaite got up and looked outside; he saw William Gillard fire a second shot into the air from a handgun. Postlethwaite tried unsuccessfully to wake Ensign.
The next thing Postlethwaite recalled was hearing the back door slammed open. He heard heavy steps “[l]ike horses trampling” and then a shot was fired.
Someone grabbed Postlethwaite’s hair and pulled his head back. His assailant put a gun against his temple, shot him, and threw him to the floor. Postlethwaite then saw the gunman aim at Denise Maxwell’s head and fire, killing her. Postlethwaite recognized the gunman as John Gillard.
Larry Beck, a neighbor, heard two gunshots between 3:00 and 3:30 a.m. At 4:15, he heard “at least two people” going towards 213 Kennet Court. About twelve minutes later, he heard more gunshots and heard two men running away from 213 Kennet Court.
At approximately 4:50 a.m., Canton police officer Sheldon Godshall arrived. Godshall asked Postlethwaite who had shot him. Postlethwaite said, “Dirty John.” Godshall asked, “Dirty John who?” and Postlethwaite replied, “Dirty John Gillard.” Another officer found Leroy Ensign’s body lying near the entrance of the house.
On January 4, Ronald Webb, his wife, and Donald Gorby were in the kitchen of Webb’s downstairs apartment in a two-family house in Wellsburg, West Virginia, when John Gillard came to the door. Webb testified that Gorby introduced Gillard to him as “Butch Johnson.” At Gillard’s request, Mrs. Webb cut Gil-lard’s hair.
While Gillard was there, Milton Smith, who lived upstairs with Gorby, entered the kitchen, saw Gillard, and said: “Jesus Christ, I didn’t recognize you with *888 out the beard, Dirty John.” Smith and Gillard went upstairs. They eventually came back down to the kitchen, where Smith told Webb “ * * * to keep him there and party with him and don’t let him go nowhere, don’t take him outside that house, don’t take him to no bars.” Smith then left.
As they talked, Webb mentioned to Gillard that he had “read in the paper where his brother was in jail for shooting some people in Canton.” Gillard replied: “I pulled the trigger, my brother is taking the fall.”
Later that day, Webb had a dispute with Gillard and Gorby. Webb threatened to go “to the law,” whereupon Gil-lard said, “I got to get out of here.” Webb then reported Gillard’s presence to the Brooke County, West Virginia, sheriffs office. As a result, sheriffs deputies and Wellsburg police went to the Webb residence and arrested Gil-lard. Gillard identified himself to the arresting officers as “Butch Johnson.”
John Gillard was indicted for the aggravated murders of Denise Maxwell and Leroy Ensign, and for the attempted aggravated murder of Ronnie Postlethwaite. In each of these three cases, two counts were returned: one charging that the offense was committed with pri- or calculation and design, R.C. 2903.01(A), and one charging felony murder, R.C. 2903.01(B). Each count of aggravated murder carried two death specifications: one charging a course of conduct involving the purposeful killing of two or more people, R.C. 2929.04(A)(5); and one charging murder coupled with aggravated burglary, R.C. 2929.04(A)(7). A seventh count charged Gillard with aggravated burglary, R.C. 2911.11.
Gillard’s alibi defense consisted of testimony that he and Jerri Oney had been at the home of Tracy and Melissa Price between 10:30 p.m., December 31, and 4:30 a.m., January 1, and had gone directly from there to Oney’s house. Oney and the Prices corroborated this account. Gillard admitted going to Wellsburg and meeting Webb, but denied introducing himself as “Butch Johnson” and telling Webb that he had been “the trigger man.” Gillard also denied that Mrs. Webb had cut his hair.
Gillard was convicted of aggravated murder, attempted aggravated murder, and aggravated burglary in 1985. The jury recommended death, which the trial court accepted and sentenced Gillard accordingly. In 1987, however, the Ohio Court of Appeals vacated Gillard’s convictions due to prosecutorial misconduct and the trial judge’s failure to recuse himself.
See State v. Gillard,
No. CA-6701,
Upon Gillard’s appeal to the Ohio Supreme Court, he submitted a new claim: his trial counsel labored under a conflict of interest. The Ohio Supreme Court remanded the case to the trial court to conduct an evidentiary hearing.
See State v. Gillard,
Thereafter, Gillard’s petition for state post-convietion relief was denied by the trial court, and the Ohio Court of Appeals affirmed.
See State v. Gillard,
Nos. 1997CA00318
&
1997CA00410,
In 1999, Gillard sought habeas relief in federal court under 28 U.S.C. § 2254. The district court granted relief on two claims: Gillard’s counsel acted under a conflict of interest so as to render ineffective assistance, and the cumulation of errors at trial resulted in the denial of Gillard’s constitutional rights. Gillard’s remaining fifteen claims were rejected as meritless. The Warden appealed and Gillard filed a cross-appeal. The district court and this court granted the following seven issues for a certificate of appealability (“COA”): (1) did Gillard’s trial counsel labor under a conflict of interest; (2) should the trial court have conducted a hearing regarding trial counsel’s conflict of interest; (3) was the trial court impartial and unbiased; (4) did the prosecution suppress evidence under
Brady v. Maryland,
II. STANDARD OP REVIEW
We review a district court’s legal conclusions in a habeas proceeding
de novo
and its factual findings for clear error.
Lucas v. O’Dea,
In
Williams v. Taylor,
III. DISCUSSION
1. Gillard’s trial counsel did not labor under a conflict of interest.
Gillard’s counsel, Louis Martinez, had represented Gillard’s brother, William, who had been a suspect in the two murders, before he represented John Gillard. According to Gillard, if Martinez had not represented William he would have argued during the trial that William was the murderer. The Warden argues that Gillard is not entitled to habeas relief because his trial counsel did not have an actual conflict of interest. We agree.
Gillard has a Sixth Amendment right to conflict-free representation by his counsel.
See Smith v. Anderson,
Gillard can satisfy the above standard by showing that Martinez labored under an “actual conflict of interest.”
See Strickland,
*891
Gillard’s argument misses the mark because although Martinez had'represented William during earlier pre-trial proceedings, the charges against William were dismissed (though he remained a suspect), and when William testified at Gil-lard’s trial, Martinez was no longer representing him. Thus, Gillard fails to demonstrate that Martinez labored under any conflict of interest.
See Sullivan
Gillard also fails to prove prejudice. Although Gillard claims that Martinez missed several opportunities during the trial to shift the blame to William and portray him as the culprit, Gillard does not prove that Martinez’s successive representation adversely affected his trial performance. The Ohio Supreme Court concluded that Martinez had an adequate strategy for refusing to project William as the murderer.
See Gillard,
2. The trial court did not err in failing to conduct an evidentiary hearing at trial concerning defense counsel’s alleged conflict of interest, and such purported conflict did not mandate an automatic reversal of Gillard’s convictions.
Gillard argues that the trial court’s failure to inquire as to Martinez’s actual conflict of interest constitutes constitutional error and necessitates automatic reversal of his convictions.
See Wood v. Georgia,
*892
Although a trial court is required to conduct an inquiry where it “knows or reasonably should know that a particular conflict exists,” this obligation does not arise “when the trial court is aware of a vague, unspecified possibility of conflict, such as that which ‘inheres in almost every instance - of multiple representar tion[.]’ ”
Mickens,
The trial court did all that was required of it, and the Ohio Supreme Court’s conclusion that Martinez did not have an actual conflict was neither contrary to, nor an unreasonable application of, clearly established Federal law. Completely dissimilar to
Holloway v. Arkansas,
3. The trial court was impartial and unbiased during Gillard’s trial.
Gillard also maintains that the trial court judge, James Unger, was biased because he (1) had been a prosecutor at the time Gillard was investigated for a 1972 murder, (2) was the chief county prosecutor at the time the offenses at issue were committed and when a warrant was issued for Gillard’s arrest, and (3) received prejudicial information concerning Gillard during an ex parte hearing. 2
*893
All three claims are meritless. First, Gillard was afforded a fair trial before an unbiased judge, pursuant to the Fourteenth Amendment.
See Bracy v. Gramley,
Second, Judge Unger was the chief county prosecutor at the time Gillard committed the murders in this case, but he left that position on January 3, 1985, in order to become a judge. A warrant for Gillard’s arrest was issued on January 2, 1985, and Gillard was arrested on January 4. Gillard has completely failed to demonstrate that Judge Unger had any involvement in investigating the instant offenses during his final three days employed as the chief county prosecutor.
See Corbett v. Bordenkircher,
Third, Judge Unger presided over a witness certification hearing in which the prosecution moved to delete Ronald Webb’s name and address from the witness list or perpetuate his testimony because Gillard’s brothers had threatened Webb and his family with physical harm if he testified against Gillard.
See
Ohio R.Crim. P. 16(b)(1)(e). Judge Unger granted the prosecution’s motion to perpetuate Webb’s testimony by deposition based on these allegations. During an
ex parte
hearing,' however, the prosecutor provided Judge Unger with the following information: Gillard acted as president of the Outlaws motorcycle gang and his brothers had threatened to harm Webb, Webb’s family, and several others if they testified against Gillard in this case. Although the Ohio Supreme Court held that Judge Unger erred in refusing to recuse himself because of the particularly inflammatory nature of this information, such error was only harmless because of the overwhelming evidence of Gillard’s guilt.
See Gillard,
4. The prosecution did not suppress material and exculpatory evidence , under Brady.
Gillard additionally claims that the prosecution failed to disclose relevant information and withheld exculpatory evidence from his counsel.
See Brady v. Maryland,
“To establish a violation of
Brady,
[Gillard] has the burden of establishing that the prosecutor suppressed evidence; that such evidence was favorable to the defense; and that the suppressed evidence was material.”
Carter v. Bell,
Although the first two
Brady
prongs are satisfied, none of the withheld evidence was material. Postlethwaite’s statement that “Gillard” was the shooter is not exculpatory; rather, it would only have been somewhat useful for impeachment purposes and does not contradict any trial testimony.
See Gillard,
5. Gillard’s trial counsel was not ineffective during the mitigation phase of the trial.
According to Gillard, defense counsel was constitutionally ineffective during the sentencing phase of his trial because Martinez conducted no mitigation investigation, repeatedly told the jury that there were no mitigating factors, presented no mitigating evidence, and insinuated that the jury should impose the death penalty if it was sure of Gillard’s guilt. Martinez exclusively relied upon residual doubt as the sole mitigating factor by arguing that Gillard was innocent; however, he never requested a residual doubt instruction from the trial court. Gillard claims that several mitigating factors existed, including provocation for the offense, absence of significant criminal history, intoxication, familial relationships, supportive children, and his educational and employment background.
The same
Strickland
standard applies here.
See Strickland,
Although Gillard’s observations are accurate, we cannot resolve that Martinez was deficient in failing to investigate and present mitigating evidence on Gillard’s behalf. The Supreme Court has confirmed that residual doubts may benefit a capital defendant and are therefore appropriately considered as mitigating evidence during the sentencing phase of trial.
See Lockhart v. McCree,
Martinez’s concession that there was no mitigating evidence does not denote a complete abandonment of Gillard or abdication of advocacy.
See Martin v. Mitchell,
Given that Gillard has not pointed to any additional mitigating evidence that should have been discovered but was not and that the jury heard all mitigating evidence that Gillard wished to present, he cannot be heard to claim that his defense counsel was deficient. This is so despite Martinez’s choice not to label these facts as mitigating evidence to the jury.
See Workman v. Bell,
Nevertheless, even assuming
arguendo
that Martinez’s performance was deficient, Gillard is not entitled to habeas relief because he was not prejudiced. “For [Martinez’s] objectively unreasonable performance to constitute ineffective assistance of counsel,
Strickland
requires [Gil-lard] to prove prejudice ‘satisfied by showing a reasonable probability that but for such performance the trial outcome would have been different.’ ”
Harries,
Under the facts of this case, defense counsel’s failure to introduce any other mitigating evidence during the sentencing phase and his admission to the jury that no mitigating evidence existed do not constitute ineffective assistance of counsel. The jury was privy to this mitigating evidence during the trial’s guilt phase and Martinez was not obligated to reintroduce it.
See Cone,
The Ohio Supreme Court’s decision is not contrary to, nor an unreasonable application of, clearly established Federal law, and it did not apply
Strickland
to these facts in an objectively unreasonable manner.
See Gillard,
6. The prosecutorial improprieties during Gillard’s trial did not violate his constitutional rights.
Gillard lastly insists that prosecutorial misconduct so infected his trial with unfairness as to result in a denial of due process. According to Gillard, the prosecution unfairly attacked his character, argued prejudicial matters outside the record, offered expressions of personal belief, and made inflammatory arguments designed to enrage and unfairly prejudice the jury. During trial, the prosecution occasionally referred to Gillard as “Dirty John,” asked Gillard on cross-examination whether he was called “Dirty John” because he would “shoot an innocent sleeping woman on a couch,” questioned his membership in several motorcycle gangs, suggested that William had attempted to “fix” the trial, stated that Gillard was a “lie,” “a fraud,” and “a con” because he wore a suit during the trial, and displayed photographs of the crime scene during closing argument.
On habeas review, this court reviews claims of prosecutorial misconduct deferentially.
Darden v. Wainwright,
Considering each of the four aforementioned factors, we conclude that none of Gillard’s examples of alleged prosecutorial misconduct rises to such a level as to justify habeas relief. Initially, references to Gillard as “Dirty John” were entirely proper because that was his nickname, which was relevant because Postlethwaite had identified “Dirty John” as the shooter. Any remarks as to his nickname did not necessarily mislead or prejudice the jury. The prosecution’s inquiry regarding Gil-lard’s motorcycle gang affiliation was also proper because he acquired the nickname “Dirty John” while working on motorcycles during his youth. The information concerning Gillard’s affiliation with motorcycle gangs was elicited during cross-examination and went to his credibility. Gillard does not submit that the prosecutor lacked a good-faith basis for questioning him regarding his motorcycle gang membership.
See Gillard,
Next, the prosecution’s remarks were isolated since they occurred primarily during closing argument at the conclusion of a lengthy six-week trial.
See Millender v. Adams,
Further, although it appears that the prosecution deliberately made the complained-of remarks, this action did not render Gillard’s trial constitutionally unfair. Rather, the prosecution was only summarizing the evidence (and did not misstate it), Gillard’s testimony, and the trial’s events for the jury.
See Hutchison v. Bell,
Finally, as the Ohio Supreme Court observed, there was overwhelming evidence of Gillard’s guilt.
See Bates v. Bell,
7. The cumulation of errors at Gil-lard’s trial does not warrant habeas relief.
The Warden also contends that the district court improperly granted habeas relief based upon the cumulative effect of the errors during Gillard’s trial. While we have recognized that “[ejrrors that might not be so prejudicial as to amount to a deprivation of due process when considered alone, may cumulatively produce a trial setting that is fundamentally unfair,”
Walker v. Engle, 703
F.2d 959, 963 (6th Cir.1983), the “Supreme Court has not held that distinct constitutional
claims
can be cumulated to grant habeas relief,”
Lorraine v. Coyle,
IV. CONCLUSION
For the foregoing reasons, we AFFIRM IN PART and REVERSE IN PART the district court’s order. We REVERSE the district court’s grant of Gillard’s writ regarding ineffective assistance of counsel due to a conflict of interest and cumulative error, and AFFIRM the denial of the remainder of his writ of habeas corpus.
Notes
. Because Martinez’s health precluded him from testifying in Gillard’s post-conviction proceedings, we are unable to determine why he chose this strategy. However, it is immaterial because Martinez recognized during trial that there was no conflict, actual or otherwise.
. Gillard has procedurally defaulted the first of these three claims because he failed to raise it in his state appellate proceedings. See
Roberts v. Carter,
. The Ohio Supreme Court determined that “residual doubt [was] not an important mitigating factor in this case’’ due to the “overwhelming and convincing” evidence of Gil-lard’s guilt.
