Maybe it was a slip of the tongue or maybe it was misguided sarcasm, but Madonna called President Obama a "black Muslim" last night at a tour stop in Washington D.C. in what otherwise resembled a message of support. After praising Abraham Lincoln and Martin Luther King Jr., Madonna turned her attention to Obama, saying, "It is so amazing and incredible to think that we have an African-American in the White House!" But the pop star didn't stop there. "So y'all better vote for fucking Obama, OK? For better or for worse, all right, we have a black Muslim in the White House, OK? Now that is some shit. That's some amazing shit," she said. "It means there is hope in this country. And Obama is fighting for gay rights, OK? So support the man, goddammit!"
