Washington, June 4: President Donald Trump is not only drawing criticism from his usual political foes but also backtalk from his defence secretary, his former Pentagon chief and a growing number of Republicans. A day after Defense Secretary Mark Esper shot down Trump's idea of using active-duty troops to quell protests across the United States, retired four-star Gen. John Allen joined the chorus of former military leaders going after the president. Also Read | Social Distancing Not Required at US President Donald Trump’s Mount Rushmore Event on July 3.

And Republican Alaska Sen. Lisa Murkowski said Esper's remarks were “overdue” and she didn't know if she would support Trump in November. Although Esper's declaration was followed by the Pentagon reversing course on pulling part of the 82nd Airborne Division off standby outside Washington, the rising criticism underscored an extraordinary clash between the US military and its commander in chief. Also Read | Indian-Origin British Minister Alok Sharma, After Displaying Coronavirus-Like Symptoms, Tests Negative for COVID-19.

Both Trump and Esper also drew stinging, rare public criticism from Trump's first defense secretary, Jim Mattis, in the most public pushback of Trump's presidency from the men he put at the helm of the world's most powerful military.

Mattis' rebuke Wednesday followed Trump's threats to use the military to “dominate” the streets where Americans are demonstrating following the death of George Floyd, a black man who died when a white police officer pressed his knee into his neck for several minutes.

Trump had urged governors to call out the National Guard to contain protests that turned violent and warned that he could send in active duty military forces if they did not. Esper angered Trump when he said he opposed using military troops for law enforcement, seemingly taking the teeth out of the president's threat to use the Insurrection Act.

Esper said the 1807 law should be invoked “only in the most urgent and dire of situations.” He added, “We are not in one of those situations now.” After Esper's visit to the White House, the Pentagon abruptly overturned an earlier decision to send a couple hundred active-duty soldiers home from the Washington, DC, region, a public sign of the growing tensions with the White House amid mounting criticism that the Pentagon was being politicized in response to the protests.

Former Secretary Mattis, a retired Marine general, lambasted both Trump and Esper in an essay in The Atlantic for their consideration of using the active-duty military in law enforcement — and for the use of the National Guard in clearing out a largely peaceful protest near the White House on Monday evening.

“We must reject any thinking of our cities as a 'battlespace' that our uniformed military is called upon to 'dominate,'” Mattis wrote, referencing quotes by Esper and Trump respectively. “Militarizing our response, as we witnessed in Washington, D.C., sets up a conflict — a false conflict — between the military and civilian society.”

Trump responded on Twitter by calling Mattis “the world's most overrated General,” adding: “I didn't like his 'leadership' style or much else about him, and many others agree, Glad he is gone!” Yet another former military leader, retired Marine Corps four-star general Allen, said that events on Monday, the day Trump walked to the church, “may well signal the beginning of the end of the American experiment.”

Allen, president of the liberal-leaning Brookings Institution, contrasted the routing of the protesters in Lafayette Park with remarks by Floyd's brother, Terrence Floyd, who denounced looting that he said tarnishes his brother's memory.

Writing in Foreign Policy, Allen urged people to make their votes in November for the future of America's democracy. “It will have to come from the bottom up. For at the White House, there is no one home,” he wrote. Then, on Thursday, Alaska Sen. Murkowski said she was “really thankful” for Mattis' comments. She said she thought his “words were true and honest and necessary and overdue.”

“I felt like perhaps we're getting to the point where we can be more honest with the concerns that we might hold internally, and have the courage of our own convictions to speak up,” she said. Asked if she could support Trump for reelection, she said, “I am struggling with it.”

Days ago, Esper had ordered about 1,300 Army personnel to military bases outside the nation's capital as Trump weighed whether to invoke the Insurrection Act and send active-duty troops into the city, where the scene of large protests that devolved into violence and looting over the weekend.

But after a night of calm enforced by a large deployment of National Guard troops and heavily armed federal law enforcement agents, defense officials said the troops would begin returning to their home base.

Army Secretary Ryan McCarthy told The Associated Press that the decision was reversed after Esper's visit to the White House. The White House didn't respond to request for comment on whether Trump ordered the change.

The shift added to confusion over the president's threat to invoke the Insurrection Act for protests following Floyd's death in Minneapolis. White House officials had indicated even before Esper's comments that Trump was backing away from invoking the act, though officials said Trump was upset that Esper's statement conveyed “weakness.”

Press secretary Kayleigh McEnany said the president was still willing to deploy federal troops despite Esper's comments: “If needed, he will use it," she told reporters.
