Obama shoos away an uninvited visitor

An uninvited White House guest today got a surprise shout-out from President Obama.

As he announced his nomination of former federal prosecutor Mary Jo White to chair the Securities and Exchange Commission, the president was upstaged by a determined housefly careening about the podium. Pausing his commendation, Mr. Obama took a few swats and carped, "This guy's bothering me here." The fly voyaged elsewhere.

Past intruders haven't been so lucky. In 2009, the president, during a CNBC interview, stopped in the middle of an answer and pulled a "karate kid" with a fly that was trying to steal the spotlight, crushing it against the back of his hand.
