Noem testifies in the Senate in her first appearance since 2 Minneapolis protesters' deaths

Her department's immigration tactics triggered a clash in Congress over its routine funding, which remains unresolved, although a spending bill passed last year granted it a significant infusion of cash for the Republican administration's mass deportation policy.

Noem defended her agency’s treatment of immigrants caught up in enforcement activities, and blamed activists and others for attacks against officers. She also lashed out at Democrats for the congressional funding showdown.

“The latest Democrat-led shutdown of DHS is reckless,” Noem said. “It’s unnecessary, and it undermines the American national security, and it harms the men and women who work at DHS and their families.”

Noem last appeared in Congress in December. But since then, President Donald Trump's immigration agenda and its enforcement by Noem's department have met fierce resistance in Minnesota, culminating in the deaths of two protesters, both U.S. citizens, at the hands of federal immigration officers.

In what was initially billed as an effort to root out fraud in Minnesota, Homeland Security eventually sent hundreds of officers from Immigration and Customs Enforcement and Customs and Border Protection to the state. They were met by protesters who organized marches, patrolled neighborhoods for ICE activity with whistles and ferried food to immigrants too afraid to leave their homes.

Renee Good was shot and killed by an ICE officer on Jan. 7, setting off intense protests by Minnesota politicians and residents pushing for Homeland Security to end its operation in the state. Then on Jan. 24, Customs and Border Protection officers opened fire on another Minnesota resident, Alex Pretti, who had been filming enforcement operations.

Those deaths led to cries for accountability and transparency. Noem, whose initial comments portrayed both Good and Pretti as the aggressors, has come under withering criticism by Democrats and even some Republicans, who have called for her to resign.

After public outrage over the deaths, Trump sent border czar Tom Homan to Minneapolis to take control of operations on the ground there. Homan has since announced a drawdown of the ICE and CBP officers who had been sent to Minnesota to carry out what had been dubbed Operation Metro Surge, although he's been adamant that the president's mass deportation agenda will continue.

Noem faced questioning from Democrats who say officers under her control have abused their power, used excessive force and violated people's constitutional rights in carrying the Trump administration's agenda.

Sen. Dick Durbin of Illinois, the top Democrat on the committee, repeatedly questioned Noem about comments she made immediately after the deaths of both Good and Pretti that cast them as the aggressors in the events leading up to their deaths. He called on her to apologize.

“You and your agency rushed to brand these victims as, quote, domestic terrorists," Durbin said. “We have ample video evidence and eyewitness testimony proving you are wrong. Your statements caused immeasurable pain to these families.”

Noem said she was relying on information from people on the scene and blamed “violent protesters” for contributing to the chaos officers encountered.

“I was getting reports from the ground from agents at the scene, and I would say that it was a chaotic scene, as you’ve seen in Minneapolis and St. Paul," she said. Her officers “worked at targeting the worst of the worst” and many times faced violence from protesters, she added.

Homeland Security has often blamed conflicts in places like Minneapolis and Chicago where it's carrying out immigration enforcement activities as the fault of Democratic politicians who they say encourage people to oppose officers as they try to make arrests.

Noem is also slated to appear Wednesday in front of a House committee.
