Washington (CNN) - Former President Bill Clinton is heading to Pennsylvania today to try and keep a Senate seat in Democratic hands. The event, a late addition by Rep. Joe Sestak's campaign, comes on the same day that Vice President Joe Biden heads to his native Pennsylvania to help out Sestak, the Democrats' Senate nominee in the Keystone state.
The former president will join Sestak at the Kaiserman Jewish Community Center in Wynnewood, Pennsylvania, in suburban Philadelphia. Sestak, a retired Navy admiral, served on the National Security Council during the Clinton administration.
Monday evening Biden is scheduled to help raise campaign cash for Joe Sestak at a fundraiser in the Philadelphia area. The Biden and Clinton events come just one week before President Barack Obama is expected to be the main attraction at a September 20 fundraiser to raise money for the two term representative.
Last year the former admiral and congressman from southeast Pennsylvania challenged Republican turned Democrat Sen. Arlen Specter for their party's nomination. Obama and Biden both supported Specter. But Sestak survived a nasty intra-party battle and defeated Specter in the May 18 primary.
Top White House officials, including Chief of Staff Rahm Emanuel, also became involved in a huge controversy over whether they used former President Clinton to dangle before Sestak an advisory job in the executive branch in exchange for him dropping out of the primary contest.
Sestak refused the offer while White House officials have denied that any laws or ethical regulations were breached, and Sestak's campaign staff now says it's time for Democrats to put everything behind them.
Sestak finds himself trailing former Rep. Pat Toomey, the Republican Senate nominee, in both campaign cash and in the polls. Toomey was leading Sestak by nine points and ten points in two recent surveys of Pennsylvania voters.
Toomey is teaming up with a high profile surrogate of his own on Thursday. Former Pennsylvania Gov. and Homeland Security Secretary Tom Ridge is scheduled to join Toomey at a press conference at State College to talk about fiscal responsibility.
