"Mob violence goes against everything I believe in and everything our movement stands for," Trump stated in a message from the Oval Office.
"No true supporter of mine could ever endorse political violence," Trump said. "No true supporter of mine could ever disrespect law enforcement or our great American flag. No true supporter of mine could ever threaten or harass their fellow Americans. If you do any of these things, you are not supporting our movement. You are attacking it and you are attacking our country. We cannot tolerate it."
His remarks were posted from the White House's Twitter account just hours after 10 House Republicans gathered with Democrats in impeaching President Trump. Trump's personal account has been banned by Twitter.
Both Democrats and Republicans have proposed Trump encouraged violence with statements he made before the protest.
In her resignation letter, Education Secretary Betsy DeVos told Trump: "There is no mistaking the impact your rhetoric had on the situation, it is the inflection point for me."
"The President of the United States summoned this mob, assembled the mob, and lit the flame of this attack," GOP Conference Chairwoman Liz Cheney, of Wyoming, likewise said in a statement describing her support for impeachment. Others, like House Minority Leader Kevin McCarthy, R-Calif., suggested that impeaching President Trump would further divide the nation at an already stressful time.
Although Trump has generally asked for nonviolent protests, the attacks followed soon after he spoke from the Ellipse near the White House, telling masses of followers to proceed doubting the 2020 election results that gave President-elect Joe Biden the win and take that fight to the Capitol.
"I know that everyone here will soon be marching over to the Capitol building to peacefully and patriotically make your voices heard," he said.
Rebels could be seen with pro-Trump flags. At least five people have died at the protests.
With just days before Biden's inauguration, listed for Jan. 20, the FBI reportedly warned that armed demonstrations were planned at all 50 state capitals.
"In light of reports of more demonstrations, I urge that there must be NO violence, NO lawbreaking, and NO vandalism of any kind," Trump told Fox News earlier on Wednesday.
"That is not what I stand for and it is not what America stands for. I call on ALL Americans to help ease tensions and calm tempers. Thank You."
He noted that federal agencies were ordered to stop violence while thousands of National Guard members were called in to defend the nation's capital and "ensure that a transition can occur safely and without incident."
