President Trump announced Thursday that he is planning to visit Parkland, Florida, where 17 people were killed by a gunman at Marjory Stoneman Douglas High School on Wednesday. "We are all joined together as one American family and your suffering is our burden also," Trump said, addressing the victims and their families. "No child, no teacher, should ever be in danger in an American school," he added.

Trump additionally expressed a commitment to "the difficult issue of mental health," reiterating a tweet made Thursday morning when he said "neighbors and classmates" knew about the "mentally disturbed" shooter. "Answer hate with love, answer cruelty with kindness," Trump said, speaking directly to American children.

As many observed, the president did not use the word "gun" in his address. He additionally ignored a shouted question by CNN's Jim Acosta about if he will do "something about guns." The 19-year-old suspected shooter had legally purchased the AR-15 used in the attack after passing a background check within the past year.

With Nick Ayers unexpectedly taking himself out of the running to be President Trump's next chief of staff, Trump "finds himself in the unaccustomed position of having no obvious second option," The New York Times reports. Several names are being floated to replace Chief of Staff John Kelly, including White House budget chief Mick Mulvaney, Rep. Mark Meadows (R-N.C.), Treasury Secretary Steven Mnuchin, Trade Representative Robert Lighthizer, Acting Attorney General Matthew Whitaker, former New Jersey Gov. Chris Christie (R), and former Trump campaign official David Bossie.

But unusually, it's not clear who's even interested in the job. Meadows, a far-right Trump loyalist, wants the position but Trump isn't sure, Politico reports, and Mnuchin "isn't eager to take the post." Mulvaney also is "not interested in becoming chief of staff," The Associated Press reports, and The Washington Post says the White House is reluctant to move Lighthizer because of his key role in trade negotiations with China.

White House chief of staff has traditionally been a stepping stone to greater power, but Trump's first two chiefs of staff, "Kelly and Reince Priebus before him, have left as diminished and arguably humiliated figures, unable to control the wild chaos of this president's White House," Politico notes. "Priebus was marginalized and mocked before he was abandoned on an airport tarmac," and "Trump had recently stopped speaking to Kelly," who "wasn't even allowed to announce his own resignation despite a reported agreement with Trump that he could do so."

"You really do have to wonder why anybody would want to be Donald Trump's White House chief of staff given that so far it's been mission impossible," Chris Whipple, the author of a history of White House chiefs of staff, tells Politico. And Kelly's successor will also have to deal with a tough re-election campaign, an incoming Democratic House majoriy, and a special counsel investigation that is circling ever closer to the White House.

President Trump was so confident that Nick Ayers, chief of staff to Vice President Mike Pence, would be his next chief of staff that the White House has already drafted the announcement, The New York Times reports. Instead, on Sunday evening, Ayers confirmed that he is leaving the White House at the end of the year, around the same time as outgoing White House Chief of Staff John Kelly.

Ayers, 36 and the father of young triplets, reportedly agreed to be Trump's chief of staff on a short-term basis, but Trump wanted a chief of staff that would stay through the rest of his first term. Ayers will apparently head a pro-Trump super PAC from Georgia.

"For decades, the job of White House chief of staff was once among Washington's most desirable jobs — a pinnacle of access and power," Politico notes. "It's a different story under Trump. A job that was once a ticket to Washington royalty has recently become a laughing stock."

Still, advisers to Trump were "stunned by the turn of events," and "one former senior administration official called it a humiliation for Mr. Trump and his adult children, an emotion that the president tries to avoid at all costs," reports Maggie Haberman at Times. "With a head of blond hair, Mr. Ayers somewhat resembles Mr. Trump in his younger days, a fact that the president often looks for as a positive signal. The president had an unusual affinity for Mr. Ayers, telling aides who expressed concern about Mr. Ayers that he liked him."

Trump downplayed the news, tweeting Sunday night: "Fake News has been saying with certainty it was Nick Ayers, a spectacular person who will always be with our #MAGA agenda. I will be making a decision soon!" Peter Weber

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:

Trump has long made Comey, whom he fired last year, a target of his ire. Read Comey's full testimony here. Bonnie Kristian
