From the New York Times:
A House Judiciary subcommittee today authorized subpoenas for Karl Rove, President Bush's political adviser, and other senior White House officials in the investigation into the firing of eight United States attorneys.
Democrats said the subpoenas, approved on a voice vote of the panel, would not be issued immediately but could provide leverage for Congress in trying to win the testimony of the aides being sought.
"We have worked toward voluntary cooperation on this investigation, but we must prepare for the possibility that the Justice Department and White House will continue to hide the truth," said Representative Linda Sanchez of California, chairwoman of the subcommittee on commercial and administrative law.
Republicans on the subcommittee said they did not dispute the power of Congress to call the officials, but said the action was premature and smacked of politics.
"The only purpose of the subpoenas is to the fan the flames and photo ops of partisan controversy," said Representative Chris Cannon of Utah, the senior Republican on the subcommittee.
President Bush and Congress appear to be headed toward a constitutional showdown over the demands for testimony and for internal White House documents.
We are headed toward a constitutional showdown, indeed. I'd call it a constitutional crisis, all having to do with signing statements which take away the power of the Congress to make laws, with secret eavesdropping programs which take away the power of the judiciary to make sure that laws are upheld and with attempts to use the press for the political purposes of one single party through the government.
The current problem is just another example of the disrespect of the constitution this administration practices.
