ST. PAUL, Minnesota (CNN) - Sen. Joe Lieberman, the Democratic vice-presidential nominee in 2000, on Tuesday spoke up for Republican Sen. John McCain, saying the presumptive GOP nominee is capable of bringing both parties together to lead the country.
"I'm here to support John McCain because country matters more than party," Lieberman said at the Republican National Convention.
Lieberman, who has staunchly defended the Bush administration's execution of the war in Iraq, lost his Democratic primary in 2006. He then declared himself an independent and won the seat in the general election.
He has since continued to caucus with Democrats in the Senate, but maintained his support of the war effort and became an early backer of McCain's.
