Washington, Jun 6 (AP) The nation's top military officer, Gen. Mark Milley, has spoken privately with key congressional leaders as Pentagon officials come under fire for the Defense Department's role in containing protests following the police killing of George Floyd.

House Speaker Nancy Pelosi called Milley, the chairman of the Joint Chiefs of Staff, to express her concerns Tuesday, according to a person who was unauthorized to publicly discuss the private conversations and was granted anonymity.

That was the day after authorities cleared protesters near the White House so President Donald Trump could hold a photo opportunity at a nearby church. Milley and Defense Secretary Mark Esper were sharply criticized for accompanying Trump.

Milley also reached out Tuesday to Senate Democratic leader Chuck Schumer of New York, said another person granted anonymity to discuss the situation.

The outreach comes as Milley and Defense Secretary Mark Esper have tried to contain damage in the aftermath of Monday's walk with Trump. Federal authorities used smoke canisters and pepper balls to clear peaceful protesters from a park so the president and his entourage could walk to the church and Trump could pose with a Bible.

Late Friday, Esper and Milley declined a request from Democrats to appear before the House Armed Services Committee next week.

“This is unacceptable,” Rep. Adam Smith, D-Wash., the committee chairman, said in a statement Friday, joined by the panel's 30 Democrats.

“Our military leaders are sworn to be accountable to the people of this country, and Congress is constitutionally responsible for oversight,” the Democrats wrote. "They must appear and testify on these crucial matters in order to meet that responsibility.”

An informal briefing Friday with the Secretary of the Army was also canceled, according to a congressional aide who spoke on condition of anonymity to discuss a matter that had not been publicly disclosed.

The White House has prohibited officials from the administration from testifying before the House unless they have cleared any appearances with the White House chief of staff.

The protests in Washington were among those nationwide following the death of Floyd, a black man who died when a white police officer pressed his knee into his neck for several minutes.

In the call with Milley, Pelosi raised a number of issues that were spelled out in a subsequent letter to Trump seeking an accounting of “increased militarization” in response to the protests.

Schumer on Tuesday warned Milley and Esper, in a speech on the Senate floor, not to allow the U.S. military to engage in “ugly stunts” like the event the night before outside the White House.

Esper told reporters Wednesday he was not aware of the operation to clear the park and did not know he was heading into a photo op. He also distanced himself from Trump's threat to step up the military's role in quelling protests, arguing against invoking the Insurrection Act, which would allow Trump to use active-duty troops in a law enforcement role.

Milley released a message this week to military leaders stating that the Constitution “is founded on the essential principle that all men and women are born free and equal and should be treated with respect and dignity" and that it ”also gives Americans the right to freedom of speech and peaceful assembly.”

The chairman of the Senate Armed Services Committee, James Inhofe, R-Okla., defended Milley's handling of the protest.

In his own Senate speech Tuesday morning, Inhofe said he wanted to “set the record straight” after conferring with Milley before and after Monday's events. Inhofe said Milley “told me that he intends to honor his oath and uphold the delicate balance between civilians and the military, and I fully believe him.”

In her letter to Trump on Thursday, Pelosi asked the president under what authority and chain of command the troops were operating in the nation's capital, warning the approach “may increase chaos.”
