The Massachusetts Democrat, known for helping craft the Dodd-Frank reform law, may be putting his retirement on hold.

Rep. Barney Frank has said that he is interested in joining the Senate, even if temporarily. He is drawn to the idea of participating in the ongoing debates about the country's fiscal situation.

"He told the hosts of MSNBC's "Morning Joe" that he is now interested in filling the seat left open by Sen. John Kerry, who has been nominated for Secretary of State, until a special election is held later this year," writes American Banker's Victoria Finkle.

"Two weeks ago I said I wasn't interested, which is kind of like [when] you're about to graduate, and they said, 'You have to go to summer school,'" Frank said on the morning show. "That deal now means that February, March and April are going to be among the most important months in American financial [history]."
