Billionaire Warren Buffett may be the poster child for President Obama’s tax plan, but the investment tycoon insists he is not a “card-carrying Democrat.”

“I support certain Republicans,” Buffet told members of Washington, D.C.’s Economic Club Tuesday night. “Actually this year I gave money to a Republican congressman.”

While Buffett didn’t name the recipient of his rare cross-party donation, Federal Election Commission data shows that Virginia Rep. Scott Rigell was the lucky beneficiary.
