Sen. Arlen Specter (D-Pa.) earned an endorsement from the Pennsylvania chapter of AFL-CIO in his bid for a sixth term.
Specter tweeted Tuesday from his verified account @SenArlenSpecter:
"Thank you, thank you, thank you, PA AFL-CIO. I'm proud to have your endorsement and support."
The former Republican has already received the endorsement of the Pennsylvania Democratic Party.
Specter is facing a primary challenge from Rep. Joe Sestak, but poll numbers show the incumbent leading by a wide margin. Sestak has failed to attract name recognition across the state throughout the primary race.
Former Rep. Pat Toomey (R), the likely Republican nominee, is running neck-and-neck with Specter.
