Police officers who fought back against Trump supporters at the US Capitol on January 6 have given evidence about the violence and hatred they experienced.
They were testifying at the first hearing of a Congressional committee set up to investigate the attack.
Capitol police officer Harry Dunn, who is black, said he was taunted with a racial epithet by the mob.
At least 535 rioters have been arrested so far, but prosecutors have only secured a few convictions.
The inquiry is being conducted almost entirely by Democrats, after most Republicans boycotted the committee.
However, two Republicans - Liz Cheney and Adam Kinzinger - have broken ranks to join the investigation.
