(CNN) - Sen. Joe Lieberman - the Democratic vice presidential nominee in 2000 - is willing to address the Republican National Convention if it will help Sen. John McCain win in November, his office confirms to CNN.
In an interview published Tuesday night, the independent Connecticut senator told The Hill newspaper that “If Sen. McCain, who I support so strongly, asked me to do it, if he thinks it will help him, I will.”
Lieberman, who lost his Democratic superdelegate status when he was re-elected to the Senate as an independent, endorsed the Arizona senator earlier this year and has actively campaigned for the presumptive GOP nominee.
McCain has not yet asked Lieberman if he would address the Republican nominating convention in September.
