This is CNN Breaking News.

And welcome to our viewers of the United States and around the world.

I'm Pamela Brown.

Wolf Blitzer is on assignment and you're in the Situation Room.

And we begin with the breaking news.

A key congressional committee is about

to hear from Trump administration officials about global threats to the United States. Homeland Security

Secretary Christy Noem will be front and center at this annual hearing. And we're also going to hear

from the director of the National Counterterrorism Center and a top FBI official.

Noam is likely to face intense questioning, especially from Democrats on everything from the

White House's immigration crackdowns to the escalating tensions with Venezuela and more.

President Trump was asked about her yesterday.

I read a story recently. I'm unhappy with Christy. I'm so happy with it. I mean, we have a closed

border. We have a border that's the best border in the history of our country. Why would I be unhappy?

She's fantastic, actually.

CNN recently reported the White House is preparing for possible cabinet turnover after the one-year mark of Trump's second term, and DHS is among the agencies that could see change.

Well, we have an all-star group to discuss here in the Situation Room. New York Times correspondent David Sanger.

He is a CNN political and national security analyst, former Deputy Pentagon Press Secretary and

CNN Global Affairs commentator Sabrina Singh, former FBI Deputy Director and CNN Senior Law

Enforcement analysts Andrew McCabe, and former NATO Supreme Allied Commander, retired General

Wesley Clark.

Great to have all of you here with us.
