A Texas man who joined the US Capitol riot armed with a holstered pistol and threatened his own children to keep quiet about his role has been sentenced to more than seven years in prison.

Guy Reffitt, 49, was found guilty in March on five felony counts, including obstruction of an official proceeding and interfering with police in a riot.

His sentence is the longest imposed on any of the US Capitol rioters.

Nearly 900 people have been charged in the 6 January 2021 raid on Congress.

Reffitt did not actually enter the Capitol with the horde of Trump supporters who breached the complex as lawmakers met to certify Joe Biden's win in the November 2020 presidential election.

He retreated after an officer pepper sprayed him in the face, but video evidence showed Reffitt egging on the crowd and leading other rioters up a set of stairs outside the building.

Multiple videos Reffitt took on and after 6 January, in which he discussed planning and bragged about participating in the riot, were used in evidence against him.

Issuing a prison sentence of 87 months on Monday, US District Judge Dabney Friedrich said Reffitt's actions and statements were “frightening claims that border on delusional”.

An oil-field worker and recruiter for the far-right Three Percenters militia, Reffitt is said to have driven from Texas to Washington DC and led fellow Three Percenters up the main staircase to the Capitol building.

According to court papers, he had told fellow members of the militia that he planned to drag US House of Representatives Speaker Nancy Pelosi out of the Capitol building by her ankles, “with her head hitting every step on the way down”.

Reffitt was reported to the FBI by his son, Jackson, 18 at the time, who told investigators his father had threatened him.

“He said 'if you turn me in, you're a traitor,” the younger Reffitt said at his father's trial earlier this year. “And traitors get shot”.

The sentence Judge Friedrich handed down was slightly below what is recommended by federal guidelines. She also declined to apply a domestic terrorism enhancement - the first requested in a US Capitol riot case.

The Texan wore an orange prison jumpsuit at the Washington DC courthouse and listened carefully as the judge credited supportive statements from Reffitt's family for the lower sentence.

He rubbed his hand across his forehead and had a wisp of a smile, says the BBC's Tara McKelvey, who attended the hearing.

Our reporter says Reffitt's sentence shows that government prosecutors may have a harder time than expected in securing the length of custodial terms they believe US Capitol rioters deserve.

Prosecutors had sought a 15-year prison term, arguing Reffitt was “in a class all by himself" among Capitol riot defendants and other rioters were “looking to him as their leader”.

But defence lawyers had argued the attack would have happened with or without him and noted he had no criminal history.

Having declined to testify at trial, Reffitt apologised in a brief statement before his sentencing, saying he had “an issue with just rambling and saying stupid [expletive]”.

His family, including his wife, sat in the court's third row, and his daughter Peyton spoke on his behalf.

“He says a lot of things he doesn't mean. His mental health is an issue,” she said, visibly emotional.

She added: “My father's name wasn't on the flags everyone was carrying that day.

“It was another man's name,” she added in an apparent reference to former US President Donald Trump.

His wife Nicole Reffitt told reporters the trial shows that “corrupt, evil politicians here in this city” are trying to undermine US civil liberties.

“This isn't just about Guy Wesley Reffitt. This isn't about just January 6th. This is about our liberties being stomped on,” she argued. (BBC)
