WASHINGTON (AP) – President Donald Trump’s Pentagon chief shot down his idea of using active-duty troops to quell protests, but then reversed course and kept the 82nd Airborne Division on standby in the Washington, D.C., region. It was an extraordinary clash between the U.S. military and its commander in chief. Defense Secretary Mark Esper angered Trump early Wednesday when he said he opposed using military troops for law enforcement. After his subsequent visit to the White House, the Pentagon abruptly overturned an earlier decision to send a couple hundred active-duty soldiers home from the D.C. area.
