Former President Trump reacted after a manhunt was launched Thursday by law enforcement officials after an Arizona man allegedly threatened to kill the Republican presidential candidate, who held a campaign event at the southern border in Cochise County.

Ronald Lee Syvrud, 66, of Benson, was taken into custody Thursday without incident, a Cochise County Sheriff's Office spokesperson confirmed with Fox News Digital.

Fox News senior correspondent Alicia Acuna asked Trump whether the threats against him made him want to change the way he does events. 

"I've heard about that. But I have to do my job," he said. "It's a job. It's a dangerous job, but I have to do my job."
