Yesterday, the Bush administration failed to meet the deadline for subpoenas from the Senate. That's really not a surprise. However, Dick Cheney sent separate responses and apparently still contends he's not part of the executive branch:

Vice President Dick Cheney’s office on Monday responded separately from the White House to a Senate subpoena for documents on warrantless wiretapping and resurrected the controversial contention that Cheney is not part of the executive branch.

Senate Judiciary Committee Chairman Patrick Leahy (D-Vt.) set Monday’s subpoena deadline after granting an extension request by the White House. Presidential counsel Fred Fielding, as expected, told Leahy in a letter that a second delay, until after Labor Day, would help Congress and the administration “expeditiously seek a means of accommodation that will negate the need for an assertion of executive privilege.”

So is Cheney refusing to answer a subpoena from his Senate colleagues? He really thinks he is a fourth branch of government.
