WASHINGTON — Homeland Security Secretary Kristi Noem defiantly defended the Trump administration's hard-line immigration policies on Thursday during a House committee hearing, portraying migrants as a major threat faced by the nation that justifies a crackdown that has seen widespread arrests, deportations and a dizzying pace of restrictions on foreigners.
Noem, who heads the agency central to President Donald Trump's approach to immigration, received backup from Republicans on the panel but faced fierce questioning from Democrats — including many who called for her resignation over the mass deportation agenda.
The secretary's testimony was immediately interrupted by protesters shouting for her to stop Immigration and Customs Enforcement raids and ''end deportations." They trailed her down the halls as she left early for another engagement, chanting, ''Shame on you!''
But she vowed she ''would not back down.''
''What keeps me up at night is that we don't necessarily know all of the people that are in this country, who they are and what their intentions are,'' Noem said.
The hearing was Noem's first public appearance before Congress in months, testifying at the House Committee on Homeland Security on ''Worldwide Threats to the Homeland,'' and it quickly grew heated as she emphasized how big a role she believed immigration played in those threats. It focused heavily on the Trump administration's immigration policies, whereas in years past the hearing has centered on issues such as cybersecurity, terrorism, China and border security.
Rep. Bennie Thompson, the panel's ranking Democrat, said Noem has diverted vast taxpayer resources to carry out Trump's ''extreme'' immigration agenda and failed to provide basic responses as Congress conducts its oversight.
''I call on you to resign,'' the Mississippi congressman said. ''Do a real service to the country.''
