PHILADELPHIA – Arlen Specter, 82, the longest-serving United States senator in Pennsylvania history, a driven, often contentious figure who placed himself at the center of national controversies for a half-century, from the Kennedy-assassination investigation in the 1960s to the passage of the economic stimulus package in 2009, died Sunday morning in his Philadelphia home.
Specter, who had served five terms before losing a re-election bid in 2010, died from complications of non-Hodgkin lymphoma.
