Pennsylvania Sen. Bob Casey plans to endorse Sen. Barack Obama for president today in Pittsburgh, sending a message both to the state's primary voters and to undecided superdelegates who might decide the close race for the Democratic presidential nomination.
Dan Pfeiffer, deputy communications director for the Obama campaign, confirmed that Casey would announce his support during a rally at the Soldiers and Sailors Military Museum and Memorial and that he would then set out with the Illinois senator on part of a six-day bus trip across the state.
