We saw some really remarkable reaction from some senior Republicans, who otherwise have tried to support the Trump administration.

Let's look at this quote from Chuck Grassley, the senator from Iowa, who until recently was the chairman of the Judiciary Committee. He spoke in an interview, I believe to The Washington Post.

He said: "The president has to have some stability. He's pulling the rug out from the very people that are trying to help him accomplish his goal."

Chuck Grassley is talking not just about the change in Homeland Security, but all these other acting departments that I know you talked to Amna and to Yamiche about yesterday.

And the one you mentioned right now, the USCIS, is important as well, because that's something that Republicans want to use, that's an office they want to use in the future for trying to deal with asylum policy.

Grassley is not the only one. I also talked to Ron Johnson, the chairman of the Senate Homeland Security Committee, Republican, same thing, concerns.

And one more really important name, chairman of Armed Services, James Inhofe, he told me this is a huge problem now because also open is, of course, the seat at the Pentagon. The defense secretary nominee is acting.

Inhofe told me, because of this, he thinks that there will be news on that nomination this week. It puts pressure to put someone in the Pentagon, because there's no one at Homeland Security.
