In about two weeks, former Illinois Governor Rod Blagojevich will report to prison in Littleton, Colo. where he is expected to stay for about 14 years. Despite two trials and convictions on 18 corruption charges, his wife maintains that her husband is innocent.

In an interview with Rosie O'Donnell scheduled to air Wednesday, Patti Blagojevich tearfully tells the talk show host and actress that she is "positive" her husband is not guilty.

"He was found guilty of getting advice and having routine conversations," she told O'Donnell, according to CBS Chicago. “I was there, and I’ve heard all the conversations. I know his heart. So much of this case was intent — what was his intent? And I know his heart.”

O'Donnell, who hosts her own show on the Oprah Winfrey Network from Chicago's Harpo Studios, told Patti Blagojevich that she "can't fathom" what she was going through as a mother. The former Illinois First Lady said she urged her two daughters to "get all of those feelings out" before their father begins his sentence, the Chicago Sun-Times reports.

"Having a child removed from their father is going to be a devastating thing," O'Donnell told her, according to NBC Chicago. "And you can help them through it, Patti, but he has to help you as well."

Rod Blagojevich was convicted last year of 18 corruption charges, including allegedly trying to sell President Barack Obama's vacant Senate seat.

The interview will air Wednesday on OWN.
