Rep. Alexandria Ocasio-Cortez (D-NY) started another feud with Rep. Marjorie Taylor Greene (R-GA) after the Georgia Republican’s appointment to a new government committee.

Greene was named chairwoman of the Subcommittee on Delivering on Government Efficiency this week. The new committee will work in tandem with President-elect Donald Trump’s new Department of Government Efficiency, led by Elon Musk and Vivek Ramaswamay, to reduce bureaucratic waste.
