Madonna Calls Obama a ‘Black Muslim’ During Concert in DC (VIDEO)

Madonna is no stranger to controversy-especially when she's on tour.

Last night during the North American leg of her blockbuster MDNA Tour, Madonna gave a spiel about Abraham Lincoln fighting for freedom and later being killed because that's what they do to "all the prophets." She then went on about Martin Luther King Jr. also fighting for freedom and being murdered as a result.

She then got the crowd even more rowdy by stating that "it's so amazing and incredible to think that we have an African-American in the White House, so those fine human beings did not die for nothing."

She told her audience they better Vote for Obama because "for better or for worse, we have a black Muslim in the White House."

She said it jokingly, of course, mocking moot claims that Obama is Muslim and not Christian.

Madonna has been a long-time supporter of Obama, even incorporating a video montage of him in a segment of her 2008 Sticky and Sweet Tour. She's well-known for turning her concerts into political statements and sparking controversy. There still four more months left on the tour, so who knows what she'll do next.

Gawker reported that she later took off her clothes to reveal "OBAMA" written on her back. And in true Madonna form, said "When Obama is in the White House for a second term, I'll take it all off."
