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.

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

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.

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

Mick Mulvaney, acting White House chief of staff in Trump’s first term, said the administration's reset on its immigration crackdown is the most significant pivot Trump's ever made, and it's the right response to the public furor that's arisen over the killings of two US citizens in Minneapolis.
