Arlen Specter Hospitalized With 'Serious' Condition

Former Sen. Arlen Specter has been hospitalized with a "serious illness," friends and family of the Pennsylvania lawmaker confirmed to the Philadelphia Inquirer and Daily News on Monday.

According to the Inquirer's Dan Gross, sources declined to comment on the nature of the 82-year-old's condition.

In 2005, Specter was diagnosed with Hodgkin's disease. The cancer returned in 2008, but was detected early. Specter returned to the Senate shortly after the cancer went into remission.

Specter, who switched party affiliation from Republican to Democrat in 2009, retired from the Senate after losing his 2010 Democratic primary to Joe Sestak. He served in the Senate for 30 years.
