Hello and welcome to the US politics live blog.

House minority leader Hakeem Jeffries has said that leadership change is not enough to reopen the government and starting to fund the Department of Homeland Security again.

It comes as Republican Senator Thom Tillis said he believes White House adviser Stephen Miller “should go” and that his role in the Trump administration has been a “big problem”.

The senior senator representing North Carolina, when asked on CNN’s State of the Union if he thinks Miller should go, during a conversation about the administration’s immigration crackdown, responded to host Jake Tapper stating “Oh, of course I do.”

“He is not worried about substance. He’s more worried about form, but I also think that he has an outsized influence over the operations of the cabinet. And I believe we’ve got qualified cabinet members there that sometimes are doing less than what they want to, because of his direction and his outsized influence. He’s a big problem in this administration. He has been from the beginning,” said Tillis.

Tillis affirmed support for Department of Homeland Security Secretary pick Markwayne Mullin to replace Kristi Noem, claiming he believes Mullin will be independent from Miller’s influence, even though Mullin repeated similar falsehoods about the killings by federal agents of Alex Pretti and Renee Good.

Tillis, who is not seeking re-election this year, was the first Republican to call for the resignation or firing of DHS secretary Noem.

But Jeffries said on NBC’s Meet the Press with Kristen Welker that leadership change alone is not enough.

“What we want is a situation where ICE is actually conducting itself like every other law enforcement agency in the country as opposed to using taxpayer dollars to brutalize or in some cases kill American citizens,” Jeffries said.
