Pokergate has officially come to the U.S. Senate.

A Washington Post photographer snapped a picture Tuesday of Sen. John McCain, R-Ariz., playing poker on his phone as the Senate Foreign Relations Committee heard Secretary of State John Kerry, Secretary of Defense Chuck Hagel, and Chairman of the Joint Chiefs of Staff Gen. Martin Dempsey make the administration's case on Syria.

After he was caught in the act, McCain joked about the poker game on twitter Tuesday night.

Scandal! Caught playing iPhone game at 3+ hour Senate hearing - worst of all I lost!

Today, the incident followed McCain again back to a Senate Foreign Relations Committee meeting to consider the use of force against Syria. As he took his seat, McCain waved his phone at photographers to prove he wasn't playing electronic poker again, and Sen. Bob Menendez, chairman of the committee, jokingly gave his colleague a warning about electronic games in the committee room.

"The committee has rules against electronic games," Menendez quipped.
