The appellants, McKinley Board, Gregory Thomas, Donnell Williams, Andre Williams *423 and Derrin Perkins, were all convicted of drug conspiracy charges. They challenge the district court’s denial of their motion for new trial based on a letter allegedly written after trial by government witness Stepfoun Hartwell that purported to recant Hartwell’s trial testimony and to describe witness tampering by prosecutors. At the new trial hearings Hartwell refused to tеstify invoking his right against self-incrimination under the Fifth Amendment to the United States Constitution. The appellants contend that the district judge erred in failing to secure Hart-well’s testimony either by granting him use immunity from prosecution or by finding he had waived his Fifth Amendment privilege. We hold that the district judge lacked authority to grant immunity without a request from the United States Attorney and that neither the letter nor Hartwell’s trial testimony constituted waiver of his Fifth Amendment privilege.
I.
The appellants were defendants in the second of four trials of members of the “R Street Crew,” so called because they sold narcotics near the intersection of R Street and Lincoln Road in Northeast Washington, D.C. Among the government’s trial witnesses were Hartwell, Frankie Pelham, Kenneth Sparrow and William O. Mayo, each of whom testified about his dealings with members of the R Street Crew. On February 11, 1993 the jury convicted all but one of the defendants of conspiracy to distribute and to possess with intent to distribute narcotics, in violation of 21 U.S.C. §§ 841 and 846, and of conspiracy to participate in a racketeer influenced corrupt organization, in violation of 18 U.S.C. § 1962(d). 1 The district judgе sentenced each convicted defendant to life imprisonment.
On January 28, 1995 Lawrence E. Freedman, a Fairfax, Virginia lawyer, sent the district judge a handwritten letter purportedly signed by Hartwell. The letter recited that prosecutors had rehearsed the author’s testimony with him' before trial and that the “majority” of his testimony had. been false and had been induced by prosecutors through bribery and threats. The letter also claimed that prоsecutors allowed Hartwell, who was incarcerated at the time, to engage in sexual activity and to use alcohol and marihuana in return for his testimony. In a cover letter Freedman stated that Hartwell had sworn to him that the letter’s contents were true.
On February 10,1995 the appellants filed a motion pursuant to Federal Rule of Criminal Procedure 33 for a new trial based on newly discovered evidence, namely Hartwell’s letter. ' Théy later supplemented the motion with written statements from Pelham, Sparrow and Mayo recanting their trial testimony and alleging similar prosecutorial misconduct. On September 12, Í995 the district judge conducted a hearing to determine whether Hartwell was willing or could be compelled to testify in the new trial proceedings. At the hearing Hartwell invoked his Fifth Amendment privilege against self-in-erimination. In an order and memorandum opinion dated September 14, 1995 the judge held that Hartwell had claimed a valid privilege and that he had not waived it.
The government subsequently filed proffers of testimony from Pelham, Sparrow and Mayo asserting that their trial testimony had been truthful and that they had neither been coerced nor received special favors or bribes from prosecutors. In addition, Sparrow’s proffer asserted that Hartwell had signed his recantation “under duress” from appellant Board. At hearings conducted on November 3, 1995 and January 4, 1996 Sparrow, Mayo and Pelham each testified that his trial testimony had been truthful and had not been influenced by prosecutorial misconduct. The district judge issuеd a memorandum opinion on September 6,1996, denying the motion for new trial and again concluding that Hart-well’s Fifth Amendment privilege protected him from testifying.
II.
The appellants challenge the denial of their motion for new trial on the grounds that (1) *424 the district judge should have granted Hart-well use immunity and (2) Hartwell'waived his Fifth Amendment privilege.
Immunity
The appellants first assert the district judge erred in not granting Hartwell use immunity from prosecution for his testimony at the new trial hearings, thereby averting the possibility of self-incrimination and the need to invoke the Fifth Amendment. We disagree.
It is . true that a district judge is authorized by statute to immunize , a witness claiming a Fifth Amendment privilege — but only “upon the request of thе United States attorney.” 18 Ú.S.C. § 6003. The government made no such request of the district judge and the judge therefore lacked authority to invoke the statute.
See United States v. Doe,
Waiver
Next, the appellants assert that Hart-well waived his Fifth Amendment privilege by testifying at trial and by writing the let *425 ter. We agree with the district court that therе was no waiver.
In support of waiver the appellants, rely on
Rogers v. United States,
Finally, we conclude the recantation letter was not a waiver of Hartwell’s Fifth Amendment privilege. The appellants contend that thе letter waived Hartwell’s privilege against testifying about the truthfulness of his trial testimony just as the grand jury testimony in
Ellis
was found to have waived a witness’s privilege as to its subject-matter. In
Ellis,
however, the court emphasized the importanсe to its holding of the “credibility and. reliability” that necessarily attaches to grand jury testimony.
For the preceding reasons, the judgment of the district court is
Affirmed.
Notes
. Defendant Steve Williams was acquitted of all charges against him. Of the other defendants all but Andre Williams were convicted of other related offenses as well.
. In
Lugg
the court noted that "[s]ome cases have indicated that the government may be compelled to grant a defense witness immunity in ‘extraordinary circumstances.’ ’’
. Nor does the record show, as it did in
Ellis,
that Hartwell intended a-knowing and voluntary waiver of privilege.
