Lieberman, a four-term senator who is leaving the Senate at the end of his term, said instituting term limits would make the upper chamber "healthier."
He added that "it would make the Senate less partisan and healthier if it turned over more often."
Lieberman, who was the Democratic vice presidential nominee in 2000, also said he would like to see the Electoral College eliminated. In that race, he and former Vice President Al Gore won the popular vote, but George W. Bush captured more electoral votes.
"I would, unsurprisingly," Lieberman said of using the popular vote. "It's kind of amazing, looking back at 2000, that there was not a whimper of an attempt to end the Electoral College."
