Lawmakers in the US state of Oregon have ousted a Republican representative for his role in helping crowds breach the State Capitol in December.

Mike Nearman was removed by a vote of 59 to 1. His was the only no vote.

It marks the first time in the state's history that a sitting Oregon lawmaker has been expelled.

The Oregon riot happened just weeks before hundreds of Donald Trump supporters stormed the Capitol in Washington DC on 6 January.

Mr Nearman's removal comes days after a video surfaced appearing to show him telling protesters how to gain access to the State Capitol on 21 December.

Separate footage shows Mr Nearman opening a door to the State Capitol. He then steps around a protester "who rushed past him into the building, followed closely by a second demonstrator who held the door open for numerous other demonstrators, who also rushed in", the resolution for his removal states.

The protesters could be heard shouting "enemies of the state" and "arrest Kate Brown", the state's Democratic governor, the resolution says. There was considerable damage inflicted inside the building and police officers were injured.

In a statement released after the vote, Speaker Tina Kotek, a Democrat, said: "His actions were blatant and deliberate, and he has shown no remorse for jeopardizing the safety of every person in the Capitol that day."

"The facts are clear that Mr Nearman unapologetically coordinated and planned a breach of the Oregon State Capitol," she added.

Mr Nearman spoke briefly after the vote.

"There's no reason to hear both sides and have at least something resembling due process," he said, sarcastically, USA Today reported.

On Monday, state House Republicans had called on their colleague to step aside. Representative Christine Drazan, the state House Republican leader, said in a statement that Mr Nearman's "plan to let people into the Capitol ended with violence, property destruction and injured cops".

"This disregard for the rule of law leads us deeper into civil unrest and division. If we want to turn our state around we must hold ourselves to a higher standard as we work to lead and serve the greater good," she said.
