"That was a great question, but it would be a horrible precedent for me to answer your question just because you yelled it out," Obama said. "So, thank you very much, guys."

The president customarily calls on reporters to ask questions at press conferences. 

At an appearance before reporters in June to announce his new rules on immigration proceedings, Obama was interrupted mid-sentence by Neil Munro, a reporter for the conservative website The Daily Caller.

The president chided Munro, saying, "It's not time for questions, sir. Not while I am speaking."

Later in his remarks, a notably testy Obama addressed Munro, who had asked if his new rules — which would halt the deportation of certain illegal immigrants brought to the United States as children — was the "right thing to do for American workers."

"The answer to your question, sir — the next time I prefer you let me finish my statements before you ask that question — is that this is the right thing to do for the American people."
