Democrats accused former colleague Sen. Joe Lieberman of misleading the Republican National Convention when he addressed them in a speech Tuesday night.
Joe Lieberman felt the brunt of Democratic attacks after he said Barack Obama didn't reach across party lines.
A senior Barack Obama campaign adviser said Lieberman flat-out lied when he told delegates that Obama never successfully reached across party lines.
"Joe Lieberman ought to be ashamed of himself for some of the things he said tonight, not as a Democrat but as an American," adviser Robert Gibbs said on "Larry King Live."
