While in the formal East Room of the White House, President Obama got casual with the press corps during his press conference on Thursday.
When asked by Fox News's Ed Henry about a recent swipe that Republican presidential candidate Mitt Romney made at Obama, the president quipped, "Well, I didn't know you were the spokesperson for Mitt Romney."
Obama was joined by South Korean President Lee Myung-bak, who is in town on an official state visit.
