Democratic presidential nominee Hillary Clinton campaigned Tuesday at a voter-registration event in West Philadelphia.

At West Philadelphia High School, Clinton encouraged people to register to vote ahead of Pennsylvania's Oct. 11 registration deadline, took on Republican opponent Donald Trump and touted her economic plans.

The event is Clinton's second appearance in Pennsylvania, an important battleground state, this week.

On Monday, she campaigned with Vice President Joe Biden in Scranton, where both Biden and Clinton's father grew up.
