Ed Rendell - a big fan and friend of Clintons - will attend a Ready For Hillary PAC fundraiser for young professionals next Thursday in Philly, according to the event's Facebook page.
It will be the former mayor and governor's first involvement with the PAC.
Tickets are $20.16 for the event, which was organized by Dan Kessler, the son of prominent Democratic fundraiser Alan Kessler. He's hoping 200 people plus some other elected officials show up.
"It'd be the first woman female president, and I think that appeals to the millennial generation as something new and refreshing," Kessler said of the "Young Philly for Hillary" theme.
With the backing of Rendell, Hillary won the Pennsylvania primary in 2008 berfore losing the nomination to then-Sen. Obama.
