The US House of Representatives has voted to expel a Republican congresswoman from two committees over incendiary remarks she made before being elected last November.
Marjorie Taylor Greene had prompted baseless conspiracy theories and showed support for violence against Democrats.
Prior to the vote, she said she regretted her views, which included claims that school shootings and 9/11 were staged.
Eleven Republicans joined the Democrats to pass the motion by 230-199.
This means the Georgia representative cannot take up her place on the education and budget panels.
It is highly unusual for one party to intervene in another party’s House committee assignments.
On Thursday before the vote, Greene expressed regret for her past comments, but stopped short of an apology.
On the floor of the House, Greene said the controversial remarks were made before she ran for office last year.
“These were words of the past. These things do not represent me,” she said.
She said she had been “upset about things” happening in the US and did not trust the government when she came upon conspiracy theories online in 2018.
She sought to pin blame on the media, saying they were “just as guilty as QAnon for promoting lies”.
The Republicans did not address her continued promotion of debunked claims that former President Trump was the real winner of the 2020 election.
