White House spokesman Josh Earnest told a CBS reporter that his question was "a clown question, bro."
"One last thing," said the CBS reporter, "[British PM] David Cameron said over the weekend that the president calls him 'bro.' Is that true? And is there any other pet names he has for world leaders?"
"Well, to paraphrase a local baseball player here in Washington, D.C., that's a clown question, bro," said White House spokesman Josh Earnest.
Earnest was referring to a saying made famous by Nationals outfielder Bryce Harper.
