US congressman Greg Gianforte misled police after his assault of Guardian reporter Ben Jacobs in May, falsely stating that Jacobs had initiated physical contact and that the “liberal media … is trying to make a story”, according to the police incident report.

The records, made public on Friday, provide new details on the violent altercation that occurred on the eve of a special election to fill Montana’s sole seat in the US House of Representatives. Jacobs had approached the then candidate at his Bozeman campaign headquarters to ask a question about the Republican healthcare bill when Gianforte threw him to the ground and punched him.

The Republican was nevertheless elected the next day.
