Former Illinois Gov. Rod Blagojevich has asked a judge to nullify the lone conviction in his mostly deadlocked corruption trial, saying the jury’s decision was underpinned by errors at trial and misconduct by prosecutors.

Trial Judge James Zagel should override jurors’ verdict and acquit Blagojevich of lying to the FBI or set it aside and try him again on that charge, defense attorneys said in a motion filed at the U.S. District Court in Chicago.
