In other news from Washington, Senate Judiciary Committee Chairman Arlen Specter said he is seriously considering suing the White House over President Bush’s use of signing statements. Bush has maintained that he has the right to revise, interpret or disregard hundreds of laws on national security and constitutional grounds. Since his election, Bush has issued more than 750 signing statements — more than all previous presidents combined. Senator Specter raised the possibility of suing the White House during a hearing on the legality of presidential signing statements. At the meeting Democratic Senator Patrick Leahy called the president’s use of signing statements a grave threat to the nation’s constitutional system of checks and balances.
