The FBI didn't deploy any undercover agents to the U.S. Capitol on Jan. 6, 2021, Department of Justice Inspector General Michael Horowitz revealed in a report released Thursday that undercuts claims that the bureau played a significant role in the events that day.

But the FBI failed to take the "basic step" of canvassing its field offices for intelligence ahead of the attack, the report stated.

FBI Deputy Director Paul Abbate told investigators that the lack of a canvass was a "basic step that was missed" and that he would have expected it to have occurred, the report stated.
