Bush impeachment can start at the state legislature level

Proctoring Congress points out how, under the House’s own rules manual, a state legislature may force a start to impeachment proceedings rather than waiting on the U.S. House of Representatives to start the ball rolling.

In the House there are various methods of setting an impeachment in motion: by charges made on the floor on the responsibility of a Member or Delegate; by charges preferred by a memorial, which is usually referred to a committee for examination; by a resolution dropped in the hopper by a Member and referred to a committee; by a message from the President; by charges transmitted from the legislature of a State or territory or from a grand jury; or from facts developed and reported by an investigating committee of the House. [ House Rules Manual, section 603]

New Mexico is reportedly the state that is likely to get that ball rolling.

I list both Bush and Cheney in the links because both need to be impeached.
