Live from NPR news, I'm Lakshmi Singh. In a dramatic cabinet shake shake, President Trump's firing Homeland Security Secretary Christy Knoem.

Trump broke the news on Truth Social today that he planned to replace the battle DHS Secretary with Oklahoma Republican Senator Mark Wayne Mullen, effective March 31st.

Mullen told reporters he did not expect Trump's phone call today.

The phone call I got from the president

was right before the statement went out. NPR's Danielle Kurtzleben reports his Senate would have to

confirm Mullen. The move comes after Noam had two combative hearings on Capitol Hill this week.

She has faced bipartisan criticism over how her agency handled the immigration enforcement

surge in Minnesota, where federal agents killed two

citizens. Members also grilled Nome on department spending, for example, on a luxury jet and a border

security ad campaign. Trump said Nome will be the new special envoy to a security initiative,

including Central and South American countries. That initiative will be announced on Saturday.

Mark Wayne Mullins served in the House for a decade before becoming a senator in 2023.

Prior to becoming a lawmaker, he was a business owner and mixed martial arts fighter.

further military operations in Iran. Why are we going to war with Iran?

This vote on Iran is not a procedural vote.

It is a profoundly moral vote.
