Lieberman says he won't join Bush administration

Asked on ABC's This Week whether he is interested in a Cabinet post, Lieberman responded: " I'm not. I appreciate the floating. It's a quadrennial game here in Washington when a new administration takes shape."

The possibility of Lieberman -- a centrist who was his party's 2000 vice-presidential nominee -- leaving the Senate has turned into something of a political parlor game in his home state in recent weeks.

While Lieberman is popular in Connecticut and would have little trouble winning re-election in 2006, a possible resignation to take a Cabinet job would further boost the Senate's Republican majority -- since GOP Gov. Jodi Rell would appoint his successor.

"I do have some fundamental agreements with President Bush on America's foreign policy, and I want to give bipartisan support to those elements of the foreign policy, like what we're doing in Iraq today," Lieberman said Sunday. "But I think I can do it better in the United States Senate."
