WASHINGTON -- President Barack Obama says the White House gate-crashers got in through a "screw-up," he's unhappy with everyone involved and it won't happen again. "What I know is what everybody knows, which is that these people should not have gotten through the gate," Obama told CBS' "60 Minutes" in an interview airing Sunday night. "I was unhappy with everybody who was involved in the process," Obama said in the interview. "And so, it was a screw-up."
