Was an FBI agent present at the 6 January riot?published at 17:02 British Summer Time 20 September 2023
Garland has a tense exchange with Kentucky Republican Thomas Massie over the 6 January riot at the US Capitol and whether there were federal agents present that day.
Massie's questions are prompted by the indictment of Ray Epps, who has been accused of being a federal agent by online conspiracy theorists.
Epps, 62, was pictured outside Congress on 6 January 2021, but says he did not go in.
He was captured on several videos around the time of the unrest and in one, from the night of 5 January 2021, he was seen shouting and urging people to enter the Capitol building.
"The FBI has said Mr Epps was not an employee or an informant," he says.
