Looks as though the Democrats might force his hand: click

Here's part of it, but it is worth clicking to look at their graph:

    Following Vice President Dick Cheney's assertion that his office is not a part of the executive branch of the US government, Democratic Caucus Chairman Rep. Rahm Emanuel (D-IL) plans to introduce an amendment to the the Financial Services and General Government Appropriations bill to cut funding for Cheney's office.

    The amendment to the bill that sets the funding for the executive branch will be considered next week in the House of Representatives.

    "The Vice President has a choice to make. If he believes his legal case, his office has no business being funded as part of the executive branch," said Emanuel in a statement released to RAW STORY. "However, if he demands executive branch funding he cannot ignore executive branch rules. At the very least, the Vice President should be consistent. This amendment will ensure that the Vice President's funding is consistent with his legal arguments."
