The newspaper said Sunday it has obtained excerpts of the interview, conducted by NBC’s Matt Lauer, with Craig and his wife, Suzanne. The interview is scheduled to air Tuesday night.

Craig -- who has announced he will serve out his Senate term despite a guilty plea in connection with his arrest at a Minneapolis airport men’s room -- was one of two Senate liaisons for Romney's campaign for the 2008 GOP presidential nomination. Craig resigned the position after his arrest became public, and Romney later said Craig had “disappointed the American people."

During the NBC interview, Craig slammed Romney.

"I was very proud of my association with Mitt Romney,” Craig said. “I'd worked hard for him here in the state. I was a co-chair of his campaign on Capitol Hill. And he not only threw me under his campaign bus, he backed up and ran over me again."
