A Blagojevich lawyer steps before the 7th U.S. Circuit Court of Appeals on Friday to ask that it toss his corruption convictions.
His defense team at least wants Blagojevich's 14-year prison term reduced. It's one of the longest sentences ever imposed for political corruption in Illinois.
FBI agents arrested the then-governor five years ago this week. A jury convicted him of wide-ranging charges in 2011, including trying to profit from his power to name someone to President Barack Obama's old U.S. Senate seat.
The 56-year-old won't be at Friday's hearing in Chicago. The disgraced Democrat remains at a Colorado prison.
