U.S. President Barack Obama is known for his famously unflappable demeanor. But yesterday the commander-in-chief lost his cool with a reporter when he thought his microphone was turned off.

This is the second time in 6 days that Mr. Obama spoke his mind while his mic was still hot.

Obama, who is biracial, showed his black side following a tense interview with Dallas TV reporter Brad Watson. Mr. Obama unclipped his mic before glaring at the reporter and saying, “Let me finish my answers next time we do an interview, all right?”

Obama might have been ticked off at Watson for asking such leading questions as, “Why do you think you are so unpopular in Texas?”

The president, who is obviously feeling the heat, is under pressure to box out the GOP’s leading frontrunner, Donald Trump, in the 2012 elections.
