Washington Al Franken announced Monday that he will end his radio talk show on Feb. 14, increasing speculation that he is preparing to run for Minnesota's U.S. Senate seat in 2008.
"I'm definitely giving it serious consideration, and I plan to make a decision soon and announce that, hopefully not on the same day that Barack Obama makes his decision and announces that," Franken said on his liberal Air America radio show.
Franken disclosed his plans on the same day that Air America, which filed for bankruptcy protection last year, announced that it will be sold to Stephen Green, the founder of a New York real estate company.
The agreement with Green appears to rescue the struggling network, which has been seeking a buyer since last fall when it filed for bankruptcy reorganization after reaching an impasse with one of its creditors.
No terms of the sale agreement were disclosed. Any sale would have to be approved by the bankruptcy court.
Green is the brother of Mark Green, a longtime New York politician who has also appeared frequently as a guest on Air America Radio.
Franken will be replaced on air by Thom Hartmann, a talk show host based in Portland, Ore.
Franken, who moved from New York to Minneapolis last year, has been contemplating a race against Republican Sen. Norm Coleman. He said his last show on Feb. 14 will be "sort of a valentine," and he teased his audience by saying an announcement regarding a Senate bid could come on one of his final radio shows.
If he has made a final decision by Feb. 14, Franken said, "I'll make sure you, my listeners, are the first to know."
