President Trump's appointment of Matthew Whitaker as acting attorney general is already facing a legal challenge.

The state of Maryland is preparing to ask a federal judge to declare Whitaker's appointment illegal. This would mean Rod Rosenstein would be declared the legitimate acting attorney general, The New York Times reports. Plaintiffs argue Trump cannot "bypass the constitutional and statutory requirements for appointing someone to that office," and they are seeking an injunction.

Critics have taken issue with the fact that Whitaker did not receive Senate confirmation before being appointed as Jeff Sessions' replacement at the Justice Department. Others have argued it's constitutional for Trump to fill Sessions' role with someone who was not confirmed by the Senate, so long as it's on a temporary basis. Whitaker has been an outspoken critic of Special Counsel Robert Mueller's investigation into Russian interference in the 2016 election, and many have called for Whitaker to recuse himself from that investigation.

The court challenge is part of an unrelated Affordable Care Act lawsuit brought by the Maryland attorney general in which Sessions is named. The judge, Ellen L. Hollander, needs to replace Sessions as a defendant with his successor, which requires her to determine whether Whitaker is actually Sessions' legal successor, the Times reports.

If the judge rules Whitaker's appointment is illegal, the case would likely head to the Supreme Court, per NBC News. Brendan Morrow

Sen. Rand Paul (R-Ky.) expressed disatisfaction on Meet the Press Sunday with President Trump's selection of William Barr to be his next attorney general.

"I'm concerned that [Barr has] been a big supporter of the Patriot Act, which lowered the standard for spying on Americans," Paul said. "And he even went so far as to say, you know, 'The Patriot Act was pretty good, but we should go much further.'"

"I'm disturbed that he's been a big fan of taking people's property, civil asset forfeiture, without a conviction," Paul continued. "Many poor people in our country have cash taken from them, and then the government says, 'Prove to us where you got the cash, and then you can get it back.' But the burden is on the individual. It's a terrible thing called civil asset forfeiture. He's a big fan of that."

Paul noted he has not yet decided how he will vote on Barr's nomination. Watch the full interview below. Talk of Barr begins around the eight-minute mark, and Paul and host Chuck Todd also discuss Special Counsel Robert Mueller's investigation, Saudi Arabia, and more. Bonnie Kristian

China's Foreign Ministry has summoned the U.S. and Canadian ambassadors to China to protest the arrest of Meng Wanzhou, the chief financial officer of Huawei Technologies.

Meng was taken into custody in Vancouver, Canada, on Dec. 1, at U.S. direction. She faces extradition to the United States, where she is accused of helping Huawei, a major electronics manufacturer, evade American sanctions on Iran.

Beijing said the arrest "severely violated the Chinese citizen's legal and legitimate rights and interests," calling it "lawless, reasonless, and ruthless, and ... extremely vicious." Canada should "release the detainee immediately and earnestly protest the person's legal and legitimate rights and interests," the statement said, "otherwise it will definitely have serious consequences, and the Canadian side will have to bear the full responsibility for it."

What if the Trumps were black? That's the question asked in Saturday Night Live's trailer for Them Trumps, an imaginary new series from the makers of Empire.

Them Trumps has a solid concept and a strong line-up: President Darius Trump (Kenan Thompson), first lady Malika (Leslie Jones), Darius Jr. (Chris Redd), and L’evanka (Ego Nwodim). Where it struggles is length, as the black Trump can't seem to avoid arrest as easily as his white counterpart.

"Maybe I've done some dirty things. But I'm making America great again," Thompson's Trump rants. "And what these feds don't realize is that I'm the president, the most powerful man in the most respected office in the world. They can't lock me up, and even though I may be black—"

That's when the feds show up. Watch the full sketch below. Bonnie Kristian

The House Judiciary and Oversight Committees on Saturday evening released a transcript of former FBI Director James Comey's lengthy testimony from the day before — and President Trump, naturally, denied it all early Sunday:

A major winter storm began Saturday in southeastern states, especially North and South Carolina, and is expected to bring unusually heavy snow through Monday. "Snowfall amounts in some locations will likely exceed a foot and result in several days of difficult or impossible travel, extended power outages, and downed trees," the National Weather Service warned.

Already more than 200,000 customers in the region have lost power, the bulk of them in North Carolina, and hundreds of flights were grounded Sunday. North Carolina Gov. Roy Cooper (D) urged residents to stay safe indoors. "Snow may be beautiful, but it can also be treacherous, and I urge North Carolinians to take this storm seriously and get ready for it now," he said. Bonnie Kristian

The United Kingdom's House of Commons is scheduled to vote Tuesday on whether to proceed with Prime Minister Theresa May's plan for Brexit, the U.K.'s exit from the European Union.

But whether the vote will proceed as planned remains uncertain, as opposition inside and out May's Conservative Party makes its prospects look dim. Protest resignations from May's own government are expected Sunday and Monday, but May's office says the vote will go forward.

May has warned fellow Tories who oppose her plan that its failure may lead to a general election, a new government, and the "very real risk of no Brexit" at all.

The deal under consideration was settled with EU leaders late last month, and European Commission President Jean-Claude Juncker warned critics it is the best realistic option. Bonnie Kristian
