The president-elect then took questions, and he was asked once again about the situation in Gaza. He reiterated the point he has made several times before that he has been briefed consistently on the matter but that he would not interfere with the current president on the matter.
"We can't have two administrations running foreign policy at the same time. We simply can't do it," Mr. Obama said. "Until I take office, it would be imprudent of me to start sending out signals that we are running foreign policy."

"I can't control how people interpret what I'm saying," he said. "The silence is not a consequence of lack of concern."
