New Orleans, Jun 19 (AP) An actor impersonating President Barack Obama mocked the Republican presidential hopefuls and made jokes about the real president's biracial roots to a room full of conservative activists.

The Republican Leadership Conference turned the podium over to impersonator Reggie Brown, who drew raucous applause from the audience when he projected lewd photos of disgraced and resigned Democratic Rep Anthony Weiner yesterday.

Brown returned to Weiner when describing former House Speaker Newt Gingrich's campaign: "His supporters are dropping faster than Anthony Weiner's pants."

The room grew more uncomfortable as Brown turned to the Republican candidates who are looking to make Obama a one-term president.

Brown took a shot at former Minnesota Gov Tim Pawlenty, who missed the conference because "he's having his foot surgically removed from his mouth."

"Don't worry: it's covered under Obamneycare. Along with spinal transplants," Brown said.
