The U.S. Department of Homeland Security is ordering hundreds of additional federal officers to Minnesota amid mounting protests over the fatal shooting of a woman by an immigration agent, Homeland Security Secretary Kristi Noem said Sunday.

Noem, speaking on Fox News’ Sunday Morning Futures, said the newly announced deployment would begin Sunday and Monday, adding to roughly 2,000 federal officers already in the Minneapolis–St. Paul area.

The increased federal presence comes after tens of thousands of people marched against ICE in Minneapolis this weekend, and more than 1,000 rallies were planned nationwide after the shooting of 37-year-old Renee Good by an Immigration and Customs Enforcement (ICE) officer earlier in the week.

Minnesota officials argue that the shooting was unjustified, pointing to bystander video they argue shows Good’s vehicle moving away from the agent when she was shot. Federal officials, including Noem, counter that the agent acted in self-defense, asserting Good drove toward the officer after another agent approached her vehicle and ordered her to exit.

On CNN’s State of the Union, Noem said that there was additional video footage showing Good protesting ICE agents earlier that day, though she did not specify whether it would be released to the public.
