Independent Sen. Joe Lieberman says he will speak at the Republican convention if John McCain wants him too.
Lieberman has been one of McCain's biggest backers.
The former Democrat and McCain see eye-to-eye on the war in Iraq and many other issues.
Lieberman is a former Democratic vice presidential running mate, making his appearance at the GOP convention a major turnaround.
CBN News reporter David Brody asked Lieberman if he would be at the event.
"Well, it's not clear yet but you might just see me there," he said. "I'm not going to go to spend all my time attacking Barack Obama. I'm going to tell them all why I am for John McCain and in some sense I hope in doing so, I may convince some Independents and Democrats who may be watching or listening out there that they too should vote for John McCain."
Sources close to the McCain campaign told CBN News that decisions on who will speak at the convention have not been made.
