– President Obama's latest supporters: Harold and Kumar. Kal Penn and John Cho reprise their stoner characters in a new Obama campaign video, in which the president makes a very important phone call asking Penn's Kumar for some help. Turns out that help involves Penn—a former member of the Obama administration and currently a national campaign co-chair—hosting live streaming coverage of the Democratic National Convention, Mashable reports. This is the first time the DNC is using a livestream, USA Today reports, and it will be chock-full of celebrity guests including Marc Anthony, Elizabeth Banks, Olivia Wilde, and Zach Braff, among others. Penn—of whom Sasha and Malia Obama are reportedly big fans—already taped an interview with Michelle Obama at the Charlotte arena where the convention kicks off tonight. But Mitt Romney has a big celeb fan of his own: Nicki Minaj. Rapdose reports that a new song, "Mercy," from Lil Wayne's latest mixtape, includes Minaj rapping the line: "I’m a Republican voting for Mitt Romney, you lazy b****es are f***ing up the economy."
