Specter prepping bill to sue Bush

I haven't seen the language yet but this idea itself sounds cool. Under the current law I believe Congress has no standing on the issue, which is President's bill signing statement, which is under attack by ABA seperately.

"We will submit legislation to the United States Senate which will...authorize the Congress to undertake judicial review of those signing statements with the view to having the president's acts declared unconstitutional," Judiciary Committee Chairman Arlen Specter, R-Pa., said on the Senate floor.

Although White House's denial, I think Bush wrote in the statement to the anti-torture bill that he will reserve the right if it goes to national security.

BTW, why isn't there a single Democrat heard on this? They're afraid of losing support from Specter or so?
