Barney Frank is setting his sights on opening a gay brothel after retiring from Congress, Fox News' Greg Gutfeld has suggested.

Frank, Congress' first openly gay member, announced on Monday that he would not seek a 17th term in 2012. He said that redistricting was behind his decision to retire.

President Barack Obama thanked Frank for his decades of service and said that he would be missed in Washington.

During a segment on Fox News' The Five, Gutfeld predicted Frank's future after leaving Washington.

“Can I make a prediction?” Gutfeld rhetorically asked. “I see a memoir in eight months called Being Frank. 'Cause I think that's nice. He'll talk about being gay, struggling with his weight. And then, he's going to later after that, open up a bed and breakfast. There won't be any breakfast, it will just be beds. It'll be highly successful.”

Columnist Robert Beckel hit back: “Please, that was a little nasty, I thought.” (The video is embedded in the right panel of the page. Visit our video library for more videos.)

Gutfeld's bed and breakfast minus the breakfast is a thinly veiled reference to allegations Stephen Gobie made against Frank in 1989. Gobie told right-leaning media that he ran a prostitution ring out of Frank's basement apartment with his approval and knowledge. Frank denied the allegations.
