US defence secretary Mark Esper said on Wednesday he does not support invoking the Insurrection Act to deploy active-duty forces to quell civil unrest for now, despite president Donald Trump's threats to militarise America's response to mass protests.
Trump said this week he could use military forces in states that fail to crack down on sometimes violent protests over the killing of George Floyd, an unarmed black man, at the hands of a white police officer in Minneapolis.
"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. We are not in one of those situations now," Esper told a news briefing.
"I do not support invoking the Insurrection Act."
Former defence secretary Jim Mattis, who had long refused to criticise a sitting president explicitly, on Wednesday accused Trump of trying to divide America and roundly denounced a militarisation of the US response to civil unrest.
I work very hard to keep the department out of politics, which is very hard these days as we move closer and closer to an electionMark Esper
Esper's news conference did not go over well with either the president or his top aides, an administration official said, speaking on the condition of anonymity.
To deploy the military on US soil for law enforcement purposes, Trump would need to invoke the 1807 Insurrection Act - something last done in 1992 in response to the Rodney King riots in Los Angeles.
The military has pre-positioned 1,600 active duty forces on the outskirts of Washington, D.C., to deploy if needed.
A US official said that the Army on Wednesday had been told of a decision to send some of the active duty troops back to their home base, but Esper reversed course following a meeting at the White House and discussions at the Pentagon.
Trump's threats to deploy active duty troops -- even in states that oppose its use to address civil unrest -- has stirred alarm within the US military and in Congress, where a top Republican warned it could easily make troops "political pawns"
Esper said he regretted using the term "battlespace" this week to describe areas gripped by protests.
"In retrospect, I would use different wording so as not to distract from the more important matters at hand or allow some to suggest that we are militarising the issue," he said.
Trump's threats to deploy active duty troops -- even in states that oppose its use to address civil unrest -- has stirred alarm within the US military and in Congress, where a top Republican warned it could easily make troops "political pawns."
Esper said he was unaware that he would be part of Trump's politically charged photo opportunity on Monday, when law enforcement forcibly cleared a park outside the White House of peaceful protesters so that the president could take a picture in front of a church holding a Bible.
Mattis, a retired Marine general who denies political ambitions, also took a swipe at current US military leadership for participating in the Monday photo-op and criticised use of the word "battlespace" by Esper and Army General Mark Milley, chairman of the Joint Chiefs of Staff.
In his press conference earlier, Esper acknowledged the difficulty of deploying the military without entering the political fray.
"I work very hard to keep the department out of politics, which is very hard these days as we move closer and closer to an election," Esper said.
Retired Navy Admiral Mike Mullen, the former chairman of the Joint Chiefs of Staff, said he was "sickened" to see how law enforcement -- including the National Guard -- had cleared the area and warned against over-use of the US military.
"Our fellow citizens are not the enemy, and must never become so," Mullen wrote.
