WASHINGTON (AP) — Homeland Security Secretary Kristi Noem defended her department’s immigration enforcement tactics in front of a Senate committee on Tuesday and pushed back against criticism from Democrats who say she wrongly disparaged two protesters killed by federal officers in Minneapolis earlier this year.

Brian McGinnis, a U.S. Marine veteran and North Carolina Senate candidate, protested while dressed in uniform at the testimony of several U.S. generals.

Casey Means, the health influencer tapped by President Trump to serve as U.S. surgeon general, will testify Wednesday morning before the Senate Committee on Health, Education, Labor and Pensions
