Capitol riot: 'QAnon Shaman' pleads guilty in federal court

A prominent supporter of the baseless conspiracy theory QAnon has accepted a plea deal in federal court for his involvement in the US Capitol riots.

Jacob Anthony Chansley was one of thousands of Trump supporters who attempted to prevent the US Congress from certifying the 2020 election.

Chansley pleaded guilty on Friday to one felony count of obstruction in an official proceeding.

Nearly 600 people have been charged in the federal investigation of the riot.

At least 36 defendants have to date pleaded guilty, eight of whom have pleaded guilty to felonies, according to CBS News.

Chansley became the de facto face of the siege, pictured amid the unrest in horns and a bearskin headdress, with the American flag painted on his face. He called himself the "QAnon Shaman".

QAnon is a wide-ranging conspiracy theory whose followers believe former President Donald Trump was waging a secret war against elite Satan-worshipping paedophiles in government, business and the media.
