Arlen Goes for the Throat?

Does Arlen Specter read Glenn Greenwald's blog? Several weeks ago I suggested exactly the following tactic on that blog to get more info from the Admin on its NSA domestic program(s). ...

According to Yahoo:

Without a pledge from Bush to provide more information on the surveillance program, Specter filed an amendment to a spending bill Thursday that amounted to a warning to the White House.

The amendment would enact a "prohibition on use of funds for domestic electronic surveillance for foreign intelligence purposes unless Congress is kept fully and currently informed."

Specter also said he would turn the amendment into a bill and hold hearings.

"Institutionally, the presidency is walking all over Congress at the moment," Specter said. "If we are to maintain our institutional prerogative, that may be the only way we can do it."

Specter made clear that, for now, the threat was just that.
