FBI Director Chris Wray said there was no evidence that the mobs attacked the parliament building on January 6 pretending to be Trump supporters.

In a testimony before the Senate Judiciary Committee on March 2 over the Capitol Hill riots, FBI director Chris Wray was asked by commission leader Dick Durbin about whether there was any evidence.

"We don't see evidence of this yet, at least for now. That doesn't mean we'll stop looking, we keep looking, but nothing yet," said Wray.

The FBI director also confirmed that there was no evidence that the Antifa movement and other left-wing groups were involved in the Capitol Hill riots, which he described as "domestic terror".

Many of the former President Trump ever hypothesized that the extreme activists and Antifa were mixed into the crowd and pretending to support him to attack the American Parliament House on January 6.

This view was also promoted by the Republican Senator Ron Johnson in recent weeks as part of an effort to reduce criticism at former US President and the crowd to support him.

After the Jan. 6 mass protests outside the White House, Trump asked his supporters to get stronger and called for marches together towards the parliament building.

The FBI obtained messages from William Robert Norwood, in which the man from South Carolina announced he would be wearing all black to look like an Antifa member and stormed the US parliament building.

"I will be no different from an Antifa and will be out of trouble, while others are captured or shot," Norwood wrote.

Besides information about the Capitol Hill riots, the director of the FBI also claimed the agency had found no evidence of "election fraud", accusations repeatedly raised by Trump and his allies after losing Joe.

After the attack on the US parliament building on January 6, Trump faced a second impeachment trial on charges of inciting violence promoted by Democrats.
