Republicans in Congress who sign Grover Norquist's Pledge violate their oath to uphold the Constitution, specifically Article 1, Section 8 and Article VI, Section 3.
Grover's desire to “drown government in a bathtub” qualifies as eliminating the Constitutional form of government by defunding it thus making GOP signers in violation of 5-USC Section 7311(1)
In an interview with The Daily Show, Norquist admits he was 12yrs old when he wrote the Pledge that GOP Lawmakers sign thus becoming 100% beholden to Grover.
Signers of the Pledge claim they made a Pledge to Taxpayers in Congressional District yet taxpayers did not vote for Grover's Pledge to be superior to the Constitution.
Members of Congress who signed Grover's Pledge should be forced to recuse themselves from ALL Tax Legislation.
