Americans were shocked last week when health insurance CEO Brian Thompson was brazenly gunned down on a New York City street.

The man suspected of killing the CEO is 26-year-old Luigi Mangione, who reportedly annoyed his lawyer by speaking up in court. 

Mangione interrupted his own defense attorney during hearing

According to CBS News, the incident occurred on Tuesday at a Pennsylvania courthouse where Mangione is fighting extradition back to New York.

At one point during his hearing, Mangione's defense attorney attempted to explain his client's possession of face masks by suggesting that they might have been acquired in the past in order to comply with COVID regulations.

However, Mangione "loudly" interjected that he had purchased the items recently, leading the lawyer to "shush" his client and then warn "him in front of the courtroom not to say a word."

That was not Mangione's only outburst, as he was previously seen struggling with law enforcement officers and yelling as they brought him to court.

"This is completely out of touch and an insult to the intelligence of the American people and their lived experience," Mangione hollered in a viral video clip.

Fox News noted that police arrested Mangione in Altoona, Pennsylvania on Monday morning after he was spotted at a local McDonald's.

The Maryland resident was found to be in possession of a fake ID along with a firearm and silencer similar to the ones used in Thompson's murder.

Thompson's killing was greeted with celebration from some on the left, including former Washington Post contributor Taylor Lorenz.

"And people wonder why we want these executives dead," Fox News quoted Lorenz as writing in a post on the left-leaning social media platform Blue Sky.

Meanwhile, an article published by New York Magazine suggested that Thompson's killing was "inevitable," a contention which was met with pushback from Pennsylvania Democratic Sen. John Fetterman.

"The public execution of an innocent man and father of two is indefensible, not 'inevitable,'" Fetterman wrote in a social media post. "Condoning and cheering this on says more about YOU than the situation of health insurance."
