A Montana congressman misled investigators about his assault on a reporter the day before he was elected and claimed that the "liberal media" was "trying to make a story" out of it, according to documents released Friday.

U.S. Rep. Greg Gianforte, a Republican, told an officer in the aftermath of the attack that Guardian newspaper reporter Ben Jacobs had grabbed him by the wrist and pulled both of them to the floor, according to notes from a Gallatin County sheriff’s officer who interviewed the politician the night of the attack.

Multiple witnesses contradicted that account, and Gianforte later pleaded guilty to misdemeanor assault. The attack occurred the day before his victory in a May 25 special election, by which time many voters already had cast ballots by mail.

More than 100 pages of documents, photos and audio from the investigation were released under a court order following requests from The Associated Press and other news organizations.

The documents include interviews with members of a Fox News crew who were in the room with Gianforte and Jacobs at the politician’s Bozeman campaign office. They said Gianforte became enraged over what he perceived as biased coverage before body-slamming Jacobs, throwing him to the ground and punching him.
