Breaking: Specter to make announcement on card check

I've heard in the last 20 minutes from two sources that Arlen Specter is going to go to the floor of the Senate today to make an announcement with regards to the Employee Free Choice Act.

Rumor is that that he will announce he is going to be voting against cloture.

Will post more information as soon as I get it.

UPDATE: GrassrootsPA has this:

AFTER MUCH PRESSURE, SPECTER TO OPPOSE CLOTURE & PASSAGE ON CARD CHECK…

According to multiple sources, Senator Arlen Specter will vote against cloture and passage on Employee Free Choice Act legislation…

 UPDATE: The American Spectator has the story:

Grover Norquist said today that he received a call from Arlen Specter's chief of staff informing him that the Pennsylvania Senator will vote against cloture on card check, dealing a serious blow to big labor's efforts to pass the legislation that would make it easier to form unions by denying workers a secret ballot on unionization.

Specter, who has received union backing in his past campaigns, did not support the Republican filibuster of card check last time it came up for a vote, and his support was seen as essential to passing the legislation this time around.

Norquist made the announcement during remarks at a labor conference sponsored by the Capital Research Center, and I confirmed them with our own Jim Antle, who is in attendence.
