A bill becomes the rule of the land when Congress passes it and the president signs it into law, right? Not necessarily, according to the White House. A law is not binding when a president issues a separate statement saying he reserves the right to revise, interpret or disregard it on national security and constitutional grounds. That's the argument a Bush administration official is expected to make Tuesday before the Senate Judiciary Committee, chaired by Arlen Specter, R-Pa., who has demanded a hearing on a practice he considers an example of the administration's abuse of power. It's a challenge to the plain language of the Constitution," Specter said in an interview. [Bush has] challenge[d] many more statutes passed by Congress than any other president. Specter's hearing is about more than the statements. He's been compiling a list of White House practices he bluntly says could amount to abuse of executive power from warrantless domestic wiretapping program to sending officials to hearings who refuse to answer lawmakers' questions. But Specter and his allies maintain that Bush is doing an end-run around the veto process. In his presidency's sixth year, Bush has yet to issue a single veto. Instead, he has issued hundreds of signing statements invoking his right to interpret or ignore laws on everything from whistleblower protections to how Congress oversees the Patriot Act.
