I'd like to promise this will be the last post on this today... but I might be wrong. The AP:

"He's a man of principle," [Mel] Sembler, a former ambassador to Italy and Australia, said of Lieberman in a telephone interview with The Associated Press on Thursday."

Mel Sembler, a former Republican National Committee finance committee chairman, helped organize a reception that raised "about a few hundred thousand dollars" for Lieberman, who was in attendance....

Sembler, who is board chairman of the Sembler Company, a real estate and shopping center development company, said he has worked hard to raise money for [Scooter] Libby's legal defense fund.

"It's amazing to go to all this hard work when a crime never got committed," said Sembler, who also described himself as "dear friends" with Cheney.

Update: See, this is why I didn't make any promises:

This week Republican money giant Mel Sembler held a fundraiser for Lieberman in St. Petersburg. Sembler was asked if he'd ever raised money for a Democrat, and told The Miami Herald that he hadn't done so in the last 76 years. Sembler is 76 years old.
