Utah Rep. Jason Chaffetz requested information from White House Chief of Staff Reince Priebus on Tuesday about security protocols at President Donald Trump’s Mar-a-Lago estate, according to the House Oversight and Government Reform Committee.

In the letter, Chaffetz, who is chairman of the committee, asks for information about the security protocols at the estate and whether or not classified information was discussed in front of guests. It also asks who vets Mar-a-Lago guests.

Chaffetz hopes to figure out whether or not these protocols were followed when Trump, Japanese Prime Minister Shinzo Abe and their aides discussed North Korea’s missile test in front of guests on Saturday night, according to ABC News.

During the discussions, Mar-a-Lago guests photographed Trump and Abe, according to ABC News.

“I am sending a letter to Reince Priebus about what happened at Mar-a-Lago,” Chaffetz told ABC News. “I do want to understand, 'Was there classified information in a nonsecure setting?'”

Meanwhile, Chaffetz doesn’t plan on investigating former national security adviser Michael Flynn, who allegedly interacted with Russia before and after the presidential election, according to The Washington Post.

But the Office of Government Ethics has urged Chaffetz to investigate Trump’s adviser Kellyanne Conway, who promoted Ivanka Trump’s business last week, The Huffington Post reported.

On Thursday Chaffetz said Conway’s action was “wrong, wrong, wrong.”
