Democratic presidential candidate Hillary Clinton will hold a rally at the Palestra tomorrow night, her campaign announced today.

The event will begin at 10 p.m. and doors open at 8 p.m. Former President Bill Clinton is also scheduled to appear at the rally, which is free and open to the public.

The event marks a final push for supporters before Pennsylvanians vote in Tuesday’s primary. After campaigning in the Philadelphia region at the end of last week, both Clinton and her opponent, Barack Obama — who held a rally in Philadelphia that attracted a crowd of 35,000 Friday — the two have criss-crossed the state over the weekend. Obama has campaigned by train and Clinton has held a series of rallies.

Update: Chelsea Clinton will also appear at the rally.
