Adam Kinzinger and his family are getting so many death threats over his Trump criticism that his office put together a 3-minute audio clip

Rep. Adam Kinzinger says he's been getting threatening calls to his office in Washington, DC.

People have also threatened to go after him and his family.

Kinzinger is a member of the House committee investigating the insurrection.

Republican Rep. Adam Kinzinger on Tuesday released a three-minute audio clip of recent threatening calls his office has received, highlighting the increased harassment he and his family have faced in light of his participation in the House committee investigating the Capitol riot on January 6, 2021.

"Threats of violence over politics has increased heavily in the last few years. But the darkness has reached new lows," Kinzinger tweeted. "My new interns made this compilation of recent calls they've received while serving in my DC office."

In one call, a person threatened to come to Kinzinger's house and go after his wife and his newborn baby.

"I'm going to come to protest in front of your house this weekend," the caller said. "We know where your family is, and we're going to get you ... We're going to get your wife, going to get your kids."

Another caller said, "I hope you naturally die as quickly as fucking possible."

Some of the callers alluded to Kinzinger's involvement in the House committee, accusing him of lying and going against former President Donald Trump during recent hearings.

Last month, Kinzinger said he and his family had received a death threat over his sitting on the committee. He shared the letter, which was addressed to his wife, Sofia, on Twitter. "That pimp you married not only broke his oath, he sold his soul," it said, adding, "Therefore, although it might take time, he will be executed."

Citing data from the US Capitol Police, Axios reported late last month that threats against lawmakers had significantly increased in the past five years. The report said that in the first three months of the year, the Capitol Police opened cases into more than 1,800 threats.

Kinzinger and Rep. Liz Cheney of Wyoming are the only two Republicans sitting on the House select committee investigating the insurrection and Trump's involvement in attempting to overturn the results of the 2020 presidential election.

Following the recent testimony from the former White House aide Cassidy Hutchinson, Kinzinger, who's been highly critical of the former president, said Trump and his allies including House Minority Leader Kevin McCarthy were "scared."
