(CNN) -- The sentencing hearing for Rod Blagojevich is set to begin Tuesday, six months after the former Illinois governor was convicted of 17 public corruption charges.
The charges are related to Blagojevich's attempt to sell the U.S. Senate seat held by Barack Obama before Obama resigned to become president.
The hearing is expected to last two days, and the sentence could be handed down Wednesday.
Federal prosecutors have asked that Blagojevich be sentenced to 15 to 20 years in prison.
"In light of Blagojevich's extensive corruption of high office, the damage he caused to the integrity of Illinois government and the need to deter others from similar acts, the government suggests a sentence of 15 to 20 years imprisonment is sufficient but not greater than necessary," U.S. Attorney Patrick Fitzgerald wrote in court documents filed Wednesday.
Attorneys for Blagojevich had no immediate comment last week.
