President Barack Obama is hitting the campaign trail to rally support for Democratic presidential nominee Hillary Clinton in Pennsylvania, a state that has served as a firewall for her party in the past six general elections but is now viewed as competitive.
Obama is scheduled to appear Tuesday without the candidate herself. Clinton was scheduled to make a fundraising swing to California, but will take a couple of days off from the campaign trail after being diagnosed with pneumonia.
Obama will seek to generate momentum for Clinton in a race that has become uncomfortably close for many Democratic supporters. Obama will also attend a fundraiser for the Democratic National Committee in Philadelphia and then fly to New York City for a Democratic Congressional Campaign Committee fundraiser.
