The nation's top military official has apologized for taking part in President Donald Trump's walk from the White House to St. John's Church for what eventually turned into a controversial photo-op after authorities had used pepper balls and smoke canisters to disperse largely peaceful protesters.
"I should not have been there," said gen Mark Milley, the chairman of the Joint Chiefs of Staff, in a prerecorded video commencement address to National Defense University. "My presence in that moment and in that environment created a perception of the military involved in domestic politics."
"As a commissioned uniformed officer, it was a mistake that I have learned from," Milley said in the video address.
ABC News has also learned that Milley what is so upset about his role in the events that he thought about resigning, but ultimately decided he would be letting the troops down. Instead he felt the better course of action was to deliver his apology.
Milley acknowledged in his remarks that everything the senior leaders do "will be closely watched and I am not immune, as many of you saw, the result of the photograph of me at Lafayette Square last week that sparked a national debate about the role of the military in civil society."MORE: Trump calls tear gas reports 'fake news,' but protesters' eyes burned just the same
Milley, who was wearing combat fatigues, and Defense Secretary Mark Esper were the target of widespread criticism from current and former leaders for their participation in last Monday's walk-through the park to St. John's Church. A senior U.S. official said Milley had changed into the camouflage uniform from his dress uniform in anticipation of a long evening at the command center that had been set up in Washington to monitor Monday evening's protest in the capital.President Donald Trump departs the White House to visit outside of St. John's Church, June 1, 2020.

When Trump's party arrived at St. John's Church, the president posed with a Bible and then asked top officials, including Esper, to participate in a photo opportunity. Though he was nearby Milley was not asked by Trump to join in the picture.
Earlier on that Monday, Esper and Milley had pushed back strongly against Trump's demand that thousands of active duty troops be sent to the nation's capital under the Insurrection Act to quell the protest that emerged following the death of George Floyd in Minneapolis, according to a senior U.S. official.
Both succeeded in advocating that thousands more National Guardsmen from other states should be sent to reinforce the numbers of the D. C. National Guard in a show of force that would demonstrate that active duty troops were not needed. As a back-up 1,600 active duty troops were moved to areas outside of Washington, D. C., to be on standby in case they were ever needed, but they were sent home a few days later.MORE: Timeline: The impact of George Floyd's death in Minneapolis and beyond
In his commencement address, Milley said he, like many Americans, what is "outraged by the senseless and brutal killing of George Floyd."
"His death amplified the pain, the frustration, and the fear that so many of our fellow Americans live with day in, day out," Milley said.
“The protest that have ensued not only speak to his killing, but also to the centuries of injustice toward African Americans," he added. "We should all be proud that the vast majority of protests have been peaceful."President Donald Trump holds a Bible as he visits outside of St. John's Church across Lafayette Park from the White House, June 1, 2020, in Washington.President Donald Trump holds a Bible as he visits outside of St. John's Church across Lafayette Park from the White House, June 1, 2020, in Washington.Patrick Semansky/AP
"What we are seeing is the long shadow of the original sin in Jamestown 401 years ago," said Milley. "We are still struggling with racism and we have much work to do."
And that includes in the military where Milley said, "we must, we can, and we want to do better." The senior leaders of the four military services have also said that they will lead initiatives to discuss and improve race relations within the military in the wake of Floyd's death.
Earlier this week, Milley and other top Pentagon officials indicated they were open to the idea of having discussions about the renaming of 10 Army bases and facilities named after Confederate generals.
But Trump quashed that possibility on Wednesday, tweeting that "My Administration will not even consider the renaming of these Magnificent and Fabled Military installation, Our history as the Greatest Nation in the World will not be tampered with. Respect our Military!"
