ABC's Elizabeth Hartfield and Sarah Parnass report:

It's only his second day of his retirement, and already Barney Frank wants back in the game. The former Mass congressman confirmed on Friday morning that he's interested in the interim appointment to fill John Kerry's Senate seat.

"A month ago, a few weeks ago in fact I said I wasn't interested," Frank said on MSNBC's "Morning Joe" Friday. "But that deal now means that February, March and April are going to be among the most important months in American financial economy."

Frank was referring to the agreement passed in the House and Senate this week that puts America past the so-called fiscal cliff, but left the automatic spending cuts associated with the sequester slated to take shape on March 1. Another Congressional head-to-head is expected in the coming months over those cuts, and Frank said he wants to be part of that fight.

"I'm not going to be coy; it's not something I've ever been good at. I've told the governor that I would now like, frankly, to do that because I would like to be a part of that," Frank said. "Coach, put me in."

Massachusetts election law dictates that a special election must take place between 145 and 160 days after an out-going representative has vacated their seat. The special election will be one to watch, but in the interim time period it will fall on Gov. Deval Patrick to appoint an interim replacement to fill Kerry's seat upon his confirmation as secretary of state.

The former congressman doesn't seem to be interested in launching a new career. He started the interview telling Joe Scarborough he planned to "write a couple books…give lectures, do some teaching and…basically run my mouth for money."

Of the Senate appointment he said, " It's only a three-month period. I wouldn't want to do anything more. I don't want to run again."

Frank retired this year after serving the state of Massachusetts for more than 30 years in the House. Last year, he became the first sitting member of Congress to marry a same-sex partner with his wedding to James Ready. If he is appointed, Frank would likely be a reliable liberal voice in the Senate.
