Showdown

Leahy just upped the stakes:

The Senate Judiciary Committee issued a series of subpoenas to the White House, Vice President Cheney’s office, and the Justice Department today related to the National Security Agency’s warrantless wiretapping program, setting the stage for a major legal showdown between Congress and the Bush Administration.

It's perfectly possible that Bush will ignore this, too. If it goes to the courts, I assume they'll side with Bush. But it's up to Leahy to push the issue that far.
