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.

Stephen Colbert’s lineup for a series of shows to be taped on campus next week includes John Legend, Chris Matthews, Ed Rendell, Michael Nutter and Patrick Murphy, according to the NYT politics blog The Caucus.

The “Colbert Report” is filming at Penn’s Zellerbach Theatre from April 14-17, in the days leading up to Pennsylvania’s April 22 primary. Neither Hillary Clinton nor Barack Obama, the two candidates for the Democratic presidential nomination, is expected to appear on the show as of now.

Look for an interview with Colbert in today’s DP to find out what he thinks of the candidates and why he’s coming to Penn.

Update: Michelle Obama is expected on the show for Tuesday, and Hillary Clinton will be a guest on Thursday’s show.
