Republican-turned-Democratic Senator Arlen Specter will be out of a job at the close of this congressional session, putting an end to his 30-year Senate career. He lost Pennsylvania's primary election to Rep. Joe Sestak, who caused a scandal when he announced that Bill Clinton had offered him a job in an attempt to keep him from running against Specter. But sources tell ABC News that Specter has expressed an interest to the administration to remain in public service. Specter is a close friend of Joe Biden and a well-known supporter of funding for the National Institutes of Health. Republicans, however, are keeping a close watch: Specter recently switched his support in favor of Supreme Court nominee Elena Kagan, after opposing her for solicitor general last year.
