Republicans for subpoenas

I had guessed Arlen Specter would vote to issue subpoenas wiretapping documents from the White House. But I didn't imagine the two other most senior Republicans on the Senate Judiciary committee--Orrin Hatch and Chuck Grassley--would do the same. That doesn't mean, of course, that Bush or Cheney see this as any indication that they owe anything to Congress. I just think it's interesting.
