The US House of Representatives has voted to punish a Republican over incendiary remarks she made by expelling her from two committees.
Marjorie Taylor Greene had promoted baseless conspiracy theories and showed support for violence against Democrats.
Eleven Republicans joined the Democrats to pass the motion by 230-199.
Before the vote, the new Georgia congresswoman expressed regret for her views, which included claims that school shootings and 9/11 were staged.
Mrs Greene has now been stripped of her two assignments on the education and budget panels.
It is highly unusual for one party to intervene in another party’s House committee assignments.
