Rep. Jason Chaffetz (R-UT) was confronted with hundreds of people at a town hall outside of Salt Lake City, Utah, on Thursday night, where the crowd jeered at the congressman and grilled him on investigating President Donald Trump.

The audience filled almost all of the 1,000 seats in the Brighton High School auditorium, and a crowd of about 1,500 people stood outside the event, according to the Salt Lake Tribune.

At one point during the town hall, members of the audience stood up and began to chant, “Do your job!”

The crowd also pushed for officials to let the more than 1,000 people outside into the town hall, chanting, “Let them in!”

Chaffetz, the chair of the House Oversight Committee, has declined to say whether he will probe Trump’s conflicts of interest and told reporters this week that the conflict would have to “rise to a very high level” for him to do so.

Members of the audience on Thursday night pressed Chaffetz to investigate Trump.

“If you want to continue to look into Hillary Clinton, I don’t care. But why aren’t you checking out your own president?” Noor Ul-Hasan, a Democratic activist, asked Chaffetz, per the Salt Lake Tribune.

Chaffetz replied by noting that he sent a letter about Kellyanne Conway’s recent interview promoting Ivanka Trump’s fashion line, according to the Salt Lake Tribune.

He also told an audience member that Trump, as the president, is not subject to federal conflict of interest statutes.

“You’re really not going to like this part: The President, under the law, is exempt from the conflict of interest laws,” he said, per NBC News.

Chaffetz also told the crowd that he wants to eliminate the Department of Education, and he was met with boos.

Members of the audience also pressed Chaffetz on public land, the Salt Lake Tribune reported. The congressman recently pulled a bill that would have had the federal government sell more than 3 million acres of public land back to the states. He has also asked Trump to reverse President Obama’s designation of the Bears Ears National Monument.

Outside the town hall, more than 1,000 people waited to be let in and jeered Chaffetz. Protesters engaged in chants like “Chaffetz is a coward,” according to KUTV.

After the congressman left the event, some protesters remained and chanted, “We’ll be back!”
