Lieberman, the Democratic nominee for vice president in 2000, was re-elected to the Senate in 2006 as an independent but continues to caucus with Democrats. He supported Republican John McCain's presidential campaign, going as far as to criticize Obama and make a speech at the Republican National Convention.
Democrats threatened to strip him of his chairmanship of the Homeland Security and Governmental Affairs committee but instead removed him as head of a smaller environmental subcommittee.
Connecticut Democrats meet Dec. 17 and are still considering a possible censure of Lieberman for his actions during the presidential campaign.
"I will ask them to judge me by my record," Lieberman said. "Generally speaking, I've had a record, a voting record, which is really ultimately what it's about, not unlike most Democrats."
Lieberman said he believes the rift between himself and the party stemmed mainly from his support of President Bush's policy in Iraq and will close as that becomes less of an issue.
"It appears to me that the war in Iraq is coming to a successful -- I don't want to say conclusion yet, but it's moving in a way that it will not be a divisive issue either in the Democratic Party or between Democrats and Republicans in the time ahead," Lieberman said. "And therefore, I think we'll return to more normal times, which I welcome."
