White House Says Trump Prepared to Invoke Insurrection Act Steve Herman WHITE HOUSE - U.S. President Donald Trump "has sole authority to invoke the Insurrection Act" and "if needed, he will use it," White House Press Secretary Kayleigh McEnany told reporters Wednesday afternoon. Earlier in the day, Defense Secretary Mark Esper said, "The option to use active-duty forces in a law enforcement role should only be used as a matter of last resort and only in the most urgent and dire of situations." Esper added, "We are not in one of those situations now. I do not support invoking the Insurrection Act." The 1807 federal law allows the president, in dire circumstances, to deploy military and federalized National Guard troops inside the country to suppress civil disorder, insurrection and rebellion. Amid reports that the defense secretary's remarks have angered the president and top White House officials, the press secretary was asked if Trump retains confidence in the key member of his Cabinet who runs the Pentagon. "As of right now, Secretary Esper is still Secretary Esper," McEnany replied. That tepid response will further add to speculation that the defense secretary could soon be asked by the president to resign. In recent days, Trump has strongly advocated using National Guard units, which are generally under state -- not federal -- control except in the District of Columbia, to put a stop to acts of vandalism and looting in cities across the country. Emphasizing "law and order," the president has demanded that more governors use the guard units at their command. He has called governors "weak" for hesitating to order a National Guard response. .
