Last week, Jason Chaffetz sat down with Donald Trump in the Oval Office for what was, by all accounts, a cordial and productive meeting. Trump was “very sympathetic” to his proposals to reform the Postal Service and strip employment protections from civil servants, Chaffetz said, and was “in the receiving mode” as the Utah Republican implored Trump to reverse President Obama’s decision to designate some million acres of public land as a new national monument. Trump had only one precondition for the conversation: the two could not talk about Chaffetz’s job as House Oversight Committee chair—a position that empowers him to launch investigations, including into the White House.

“Before my bum even hit the chair, the president said, ‘No oversight. You can’t talk about anything that has to do with oversight,’ ” Chaffetz told Politico.

The congenial meeting was not well received back in Chaffetz’s home state of Utah, where, days later, more than 2,000 people swarmed a town hall event with the congressman, booing him for not investigating Trump’s conflicts of interest and chanting, “Do your job!”

The House Oversight chair pointed out that he had recently sent a letter criticizing Trump adviser Kellyanne Conway for promoting Ivanka Trump’s fashion line, but struggled to explain why the president was getting a pass. “You’re really not going to like this part: the president, under the law, is exempt from the conflict of interest laws,” he said.

The political calculus for Chaffetz appeared to change, somewhat, over the weekend, as the White House became embroiled in two new scandals. First, The Washington Post and The New York Times reported that Michael Flynn, then Trump’s national security adviser, had discussed easing sanctions on Russia during a pre-inauguration call with the Russian ambassador to the U.S.—despite Flynn having told Vice President Mike Pence, among other administration officials, that no such conversation had taken place. Trump and several members of his inner circle, it would later be reported, had known for weeks that Flynn had misrepresented himself, and were unsure how to respond. But the president’s uncertainty about whether Flynn could be trusted didn’t stop him from bringing him to Mar-a-Lago, the Winter White House, as he entertained Japanese prime minister Shinzo Abe. There he precipitated his second scandal when he decided that a sudden foreign-policy crisis—the launch of a North Korean test missile—should not interrupt the dinner he and Abe were enjoying on Mar-a-Lago’s leafy terrace. In full view of the resort’s paying members, Trump quickly turned the private dining hall into a makeshift situation room, as aides brought over documents and illuminated them with the flashlights on their phones.

“HOLY MOLY !!! It was fascinating to watch the flurry of activity at dinner when the news came that North Korea had launched a missile in the direction of Japan,” one member gushed on his Facebook page, sharing a photo of the president and his team hunched over laptops and making phone calls as dozens of enthralled resort-goers looked on.

Chaffetz, who spent years making political hay of Hillary Clinton’s own lax national-security protocols, took note. The Republican sent a letter Tuesday asking Chief of Staff Reince Priebus to detail what security protocols were in place at Mar-a-Lago when this played out over the weekend. He also wanted to know if guests are vetted to “ensure that they are not foreign agents or spies on behalf of a foreign government,” Politico reports. “Discussions with foreign leaders regarding international missile tests, and documents used to support those discussions, are presumptively sensitive,” he wrote. He asked the White House to respond by February 28.
