Usually, after a deadly emergency or an event that could have become one, the governor of the state where it happened somberly pledges to support the agency investigating it however he or she can.

This is not quite what happened in Florida after the apparent attempted assassination of Donald Trump on one of his golf courses over the weekend.

Instead, after the F.B.I. announced it was investigating the incident, Gov. Ron DeSantis of Florida, a Republican, announced that his state would do its own research on what had happened.

“In my judgment, it’s not in the best interest of our state or our nation to have the same federal agencies that are seeking to prosecute Donald Trump leading this investigation,” DeSantis said on Tuesday morning at a news conference in West Palm Beach, raising the possibility that the suspect, Ryan Routh, could face a state charge of attempted murder.

It is not uncommon for state and federal investigators to conduct parallel inquiries after a major event — but it is uncommon for state leaders to publicly impugn federal investigators in the process. It’s a sign of the way Sunday’s incident has become the latest front in the war that Trump’s party is waging with federal law enforcement, and the latest example of Republicans seeking to release their own version of the facts to score political points.

So today, I reached out to my colleague Patricia Mazzei, the Miami bureau chief for The New York Times, to ask about the apparent assassination attempt and DeSantis’s investigation. Our conversation was edited and condensed.

Pati, thank you so much for talking with me today. First things first: What’s the latest on the shooting?

The suspect in the case, who was detained on Sunday, made his first appearance in federal court on Monday in West Palm Beach, where he was charged with two federal gun possession crimes. The F.B.I. is leading an investigation, working with the Secret Service and various local sheriff’s offices, to sort out exactly what happened.

You have covered a lot of major news events in Florida during DeSantis’s time as governor. How unusual is it for him to announce the state’s own investigation into a matter like this?

It feels unusual in that when there is a federal crime, federal investigators usually just take the lead, and if there is a state crime to pursue, local prosecutors typically take a back seat while they wait for the federal case to resolve, or at least to move forward. The governor has made himself a national figure in the last few years by saying he’s unafraid to take on federal authority. So this plays into his political persona as someone who likes to do things his own way.

Who will run the state investigation?

DeSantis issued an executive order assigning the case to prosecutors from the office of Ashley Moody, the Florida attorney general. DeSantis is suggesting that having the state look at this is necessary because he’s unsure whether the federal investigation can be trusted — which I think is most striking
