CLEVELAND — U.S. prosecutors asked a judge Friday to reject a federal public defender’s request to represent a retired Ohio autoworker who is on trial in Germany for alleged Nazi war crimes. John Demjanjuk, 90, already has a U.S. attorney willing to work for free, so he doesn’t need a public defender, prosecutors said in a U.S. District Court filing. The public defender asked last week to be appointed co-counsel, citing a 1985 FBI report recently uncovered by The Associated Press that challenged the authenticity of a Nazi ID card used as evidence in the trial.The German court is nearing a verdict on more than 28,000 counts of accessory to murder against Demjanjuk on allegations he served as death camp guard. He denies the charges.Federal prosecutors said there are no current U.S. proceedings requiring representation for Demjanjuk. They said Demjanjuk hasn’t requested a public defender and said it was odd for the public defender to seek to have itself appointed when Demjanjuk could ask for one through his German or U.S. attorneys.The government also said the public defender’s request focused on speculation that the U.S. might be withholding evidence that could clear Demjanjuk in his German trial. The documents in question have been provided to the German court, prosecutors said.”Thus, to the extent that the documents are relevant, they have been and will be appropriately considered by the German court,” prosecutors wrote.The filing said the public defender’s allegations of tainted evidence “appear to have been included solely to sensationalize this motion and criticize the government.”The public defender, Dennis Terez, said his office would respond to prosecution comments in a court filing. No timetable was mentioned.
