Vice President Tuesday, First Lady Wednesday to campaign for Clinton in Philadelphia

PHILADELPHIA (WTXF/AP) - Hillary Clinton and her allies will be campaigning in battleground states including Pennsylvania after Monday's first presidential debate. The events will focus on registering voters.

Vice President Joe Biden will be in Philadelphia on Tuesday, which is National Voter Registration Day.

Organizers say he'll urge Pennsylvanians to register to vote ahead of the Oct. 11 deadline and kick off a volunteer voter registration drive. They also say he'll discuss his support for Clinton and share her vision for an economy that works for everyone, not just those at the top.

Doors will open to public at Drexel University's Main Building, 3141 Chestnut Street, at 9am. Biden's speech is set to start at 10:45am.

Then, First lady Michelle Obama will be making stops in Philadelphia and Pittsburgh on Wednesday.

Here, she'll attend a Democratic Party event at noon at LaSalle University. She's expected to lay out what's at stake in this election.

Some of the states Clinton's allies will be visiting -- Pennsylvania, Florida and Ohio -- have voter registration deadlines in early October.
