Specter believes that the signing statements are being used by the president to skirt recent legislation, especially the outlawing of torture of terror detainees and the revised Patriot Act, which Specter authored. It's unknown if Specter's bill has enough muster in the Senate to pass, but considering how the Senate looks very bad right now by allowing its lawmaking powers be usurped by the executive, there's probably a good chance the bill will be enacted into law.
As much as I admire this particular development, it seems diametrically opposed to another bill Specter is passing among his colleagues. In it, Specter and the Judiciary Committee reached a "compromise" with the Bush administration over NSA spying activities. According to a Washington Post editorial by Specter "The president has insisted that he was acting lawfully within his constitutional responsibilities. On its face, the program seems contrary to the plain text of the 1978 Foreign Intelligence Surveillance Act (FISA), which regulates domestic national security wiretapping. The president argues, however, that his inherent constitutional powers supersede the statute. Without knowing the exact contours of the program, it's impossible to say whether he is right or wrong. But three federal appeals court decisions suggest the president may be right." Specter also writes that the bill... "also modernizes FISA in important ways, giving the president added flexibility in protecting the country. The bill extends from three days to seven the time, in emergency situations, that the government can conduct surveillance without the court's permission. It permits the attorney general to delegate his authority to seek emergency warrants to subordinate officials. And it exempts from FISA's jurisdiction communications between two persons overseas that gets routed through domestic servers. The bill would also transfer the various lawsuits challenging the program to the FISC for consideration under its secure procedures."
So on one hand, Specter challenges President Bush's authority to ignore restrictions put on the executive branch by the legislative, and on the other, Specter extends presidential authority to continue a program that violates Constitutional protections for citizens. Pretty neat trick, eh?
Specter and Congress' disingenuousness exposes both the executive and legislative branches as being in disarray. Two branches of government are now at war over what the president can and cannot do, and that signals neither branch is capable of carrying out their Constitutional mandates. It's also a sign that our democracy is seriously fucked up. And all of this is going to continue ad nauseum unless you exercise your Constitutional duty to show Specter and the rest of the eminent leeches in Congress the door in 2006 and 2008.
