(AP)- President Donald Trump said Friday “with a high degree of certainty” that the suspect in the Charlie Kirk killing has been caught.

Federal investigators and state officials on Thursday had released photos and a video of the person they believe is responsible. Kirk was shot as he spoke to a crowd gathered in a courtyard at Utah Valley University in Orem.

More than 7,000 leads and tips had poured in, officials said. Authorities have yet to publicly name the suspect or cite a motive in the killing, the latest act of political violence to convulse the United States.

The suspect in custody in connection with the assassination of Charlie Kirk is a 22-year-old from Utah, a law enforcement official told The Associated Press.

Authorities have identified the suspect as Tyler Robinson, said the official, who spoke on the condition of anonymity because they were not authorized to discuss the ongoing investigation.
