Joe Lieberman (I-Conn.) caucus with Senate Democrats, even though Lieberman campaigned vigorously against him.

"President-elect Obama looks forward to working with anyone to move the country forward," Stephanie Cutter wrote in an e-mail to TalkingPointsMemo. "We'd be happy to have Sen. Lieberman caucus with the Democrats. We don't hold any grudges."

Lieberman's support for the Iraq war and Sen. John McCain (R-Ariz.) has made him a bete noire of liberal Democrats. Bloggers have called for him to be removed from the chairmanship of the Senate Homeland Security Committee.

But Cutter said that Obama wouldn't get involved in whether Lieberman keeps his post.

"We aren't going to referee decisions about who should or should not be a committee chair," Cutter wrote in the e-mail to TPM.
