Blagojevich's attorneys argued that a judge in a re-sentencing hearing last year gave the jury flawed instructions and didn't take in to account the former governor's rehabilitation.
The Democrat is serving a 14-year sentence in federal prison on 18 counts of corruption related to his duties as governor. Blagojevich attempted to sell to the highest bidder the Senate seat left open when former President Barack Obama won the election in 2008.
Five of his convictions have been struck down by an appeals court, and Blagojevich has been pursuing every possible avenue to get out of prison. In December he petitioned the Justice Department for a commutation, evidently hoping that Obama would grant his request before he left office.
Blagojevich, 60, is serving his time at the Federal Correctional Institution in Englewood, Colo,
The former governor starred in Donald Trump's reality TV show "Celebrity Apprentice" in 2010 while he was waiting for his court date.
