Sens. Lisa Murkowski and Thom Tillis are the first GOP members of Congress to call for Noem to step down as secretary of the Department of Homeland Security.

A handful of Democratic senators have voiced support for impeaching President Donald Trump's DHS secretary.

Secretary of Homeland Security Kristi Noem is facing internal scrutiny after the fatal shooting of Alex Pretti, multiple sources told CBS News, but she is expected to keep her job.

The Democratic lawmaker known for his independent voting record and willingness to work with the GOP slammed Noem as "betraying" the agency.
