Vice President Joe Biden is scheduled to attend a campaign event for Sen. Arlen Specter, returning to the area where he was born for the first time since taking office.
Biden will attend a rally for Specter at the Wilkes-Barre/Scranton International Airport in Avoca on Friday afternoon.
Specter faces a challenge from U.S. Rep. Joe Sestak in the May 18 Democratic primary.
Sestak, a former Navy admiral, this week denounced an ad aired by Specter saying he was relieved of duty "for creating a poor command climate.''
Sestak has called on Biden to disavow the ad as an inaccurate "Swift Boat''-style attack.
