A Republican candidate in Montana has been accused of body-slamming a Guardian reporter.

Tech mogul Greg Gianforte, who is running in the Montana special election, was recorded on audio allegedly slamming reporter Ben Jacobs to the ground on Wednesday.

Jacobs' glasses were smashed and he was carted off in an ambulance as a result.

The political reporter had been trying to ask Gianforte about his stance on healthcare when he lashed out.

The audio recording, which The Guardian swiftly published after the incident, reveals their conversation.

Jacobs took to Twitter immediately after the incident, revealing that his glasses had been broken

'I'll talk to you about that later,' Gianforte, 56, said before allegedly attacking him.

'There's not gonna be time later so...' Jacobs responded before a sudden scuffled ensued.

Gianforte roared: 'I'm sick and tired of you guys! Get the hell outta here! You're with The Guardian right?'

Jacobs was taken away in an ambulance

'Yeah and you just broke my glasses!' a shocked Jacobs replied.

'The last guy did the same thing,' Gianforte carried on, referring to another of the newspaper's reporters.

'You just bodyslammed me and broke my glasses,' the journalist said again.

The incident took place at Gianforte's campaign HQ in Bozeman, Montana. He had been setting up for an interview with a local news crew when Jacobs approached him.

Afterwards, the journalist told his own employer: 'He took me to the ground. This is the strangest thing that has ever happened to me in reporting on politics.'

Gallatin County Sheriff is now investigating the incident. Gianforte did not immediately respond to requests on Wednesday night.
