President Donald Trump said Friday that he believes, “with a high degree of certainty,” that Utah law enforcement has detained the shooter who killed right-wing activist Charlie Kirk at Utah Valley University on Wednesday.

The president made the announcement during an in-person appearance on “Fox and Friends” in New York City. NBC News confirmed the arrest with law enforcement.

“Essentially, somebody that was very close to him turned him in,” Trump told the show’s hosts. “It’s interesting, we had very good pictures, but not great, not perfect.”

Trump said he was told that the suspect’s father and a religious leader were involved in bringing the individual to law enforcement.

He praised the investigators, saying, “We started off with a clip that made him look like an ant, that was almost useless. We just saw there was somebody up there.”
