From McCain's Twitter:
A lot of people seem to be concerned that Senator John McCain was playing games on his iPhone during a Senate committee hearing on the Syria situation.
McCain is not one of those people who seems very concerned.
Scandal! Caught playing iPhone game at 3+ hour Senate hearing - worst of all I lost!— John McCain (@SenJohnMcCain) September 3, 2013
McCain's game, apparently poker, was captured by a Washington Post photographer.
McCain was paying attention at one point, when he was questioning Secretary of State John Kerry during the hearing.
The hearing, which almost hit four hours, can be seen on video here.
