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. It was Noem’s first congressional appearance since the shooting deaths of the two protesters galvanized widespread opposition to how the Trump administration is executing its mass deportation agenda, a centerpiece policy of President Donald Trump's second term. At the time, Noem portrayed the protesters, two U.S. citizens, as armed agitators, although accounts from local officials and bystander video contradicted assertions from her and other administration officials. In the hearing, Noem defended her agency’s treatment of immigrants caught up in enforcement activities, and blamed activists and others for attacks against officers. Since the deaths in Minneapolis, the administration has taken steps meant to tone down tensions, including drawing down the operation there. But the administration has continued pressing restrictions against both legal and illegal immigration, has been buying up warehouses for immigration detention and persisting in federal enforcement in areas around the country. Noem said about 650 investigators remain in Minnesota as part of a broader fraud probe.
