Mitch McConnell, the top Senate Republican, said on Monday that Rep. Marjorie Taylor Greene's embrace of conspiracy theories was a "cancer" on their party, as House Democrats moved to strip her of committee assignments.

Incendiary comments Greene made, including denying that school shootings took place and expressing support for violence, have emerged in recent days.

Democratic Rep. Debbie Wasserman Schultz introduced a resolution to remove the newly elected Republican representative from Georgia from her seats on the education and budget committees of the House of Representatives.
