Welcome to the NewsHour. Prosecutors in New York have charged the suspect in the killing of United Health Care CEO with murder as an act of terrorism, among other charges.

Luigi Mangione had already been charged with murder in the killing of Brian Thompson. The terror allegation is new.

Under New York law, such a charge can be brought when an alleged crime is intended to

intimidate or coerce a civilian population, among other factors. Manhattan's district attorney

Alvin Bragg said the brazen attack was meant to have a broader impact.

This was a frightening, well-planned, targeted murder that was intended to cause shock and attention and intimidation.

It incurred in one of the most bustling parts of our city, threatening the safety of local residents and tourists alike, commuters and business people just starting out on their day.

The killing has sparked a wave of outrage against the health care industry at large,

with police warning that there could be an elevated threat against executives,

and it's led to an outpouring of support for Mangione himself.

At a press conference this afternoon, New York

City's police commissioner compared some of the public's reaction to that of a violent mob.

In the nearly two weeks since Mr. Thompson's killing, we have seen a shocking and appalling

celebration of cold-blooded murder. Social media has erupted with praise for this

cowardly attack. Let me say this plainly. There is no heroism in what Mangione did.

The 50-year-old Thompson was shot in the early hours of December 4th while walking to a Manhattan hotel

where United Health Care was holding its investor conference.

Mangione was arrested nearly a week later in Pennsylvania.

His lawyer has said he'll fight extradition to New York to face the charges there.

An extradition hearing is scheduled for Thursday.

The day's other headlines start in Wisconsin, where officials say the motive behind yesterday's

school shooting appears to be a, quote, combination of factors. But police chief Sean Barnes provided no further details.
