The article states that Trump "sought to arrogate to himself the right to determine the propriety, scope and nature of an impeachment inquiry into his own conduct....This abuse of office served to cover up the president's own repeated misconduct and to seize and control the power of impeachment -- and thus to nullify a vital constitutional safeguard vested solely in the House of Representatives."
Jerrold Nadler, D-N.Y., said: "Within our system of checks and balances, the president may not decide for himself what constitutes a valid impeachment inquiry, nor may he ignore lawful subpoenas or direct others to do so. Many presidents have asserted privilege, but only President Trump has ordered the categorical defiance of a congressional investigation."
Calling the obstruction article "a made-up crime," Tom McClintock, R-Calif., said Trump "sought to defend his constitutional rights and those of his office. [The article] removes the judiciary from our Constitution and places Congress alone in the position of defining its own powers."
A yes vote was to impeach Trump for obstruction of Congress.
