MEMORANDUM *

Co-defendants William Villa and Roy Frisbee were convicted of drug offenses arising from their roles in a methamphetamine trafficking conspiracy that moved between 800-600 pounds of methamphetamine from California to Hawaii and distributed it in Hawaii. They argue together that the prosecution’s failure to turn over evidence the defense could have used to impeach the credibility of a cooperating witness was an error under Brady v. Maryland, 373 U.S. 83 , 83 S.Ct. 1194 , 10 L.Ed.2d 215 (1963), and Giglio v. United States, 405 U.S. 150 , 92 S.Ct. 763 , 31 L.Ed.2d 104 (1972). Villa also argues that the prosecutor impermissibly vouched for the credibility of the government’s wit *641 nesses.
