Former President Trump responded after police launched a manhunt Thursday after an Arizona man threatened to kill the Republican presidential candidate, who was holding a campaign rally on the southern border in Cochise County.

Ronald Lee Syvrud, 66, of Benson, was arrested without incident Thursday, a spokesperson for the Cochise County Sheriff’s Office confirmed to Fox News Digital.

Fox News senior correspondent Alicia Acuna asked Trump if the threats against him are causing him to change his approach to events.

“I’ve heard about it. 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.”

Cochise County Public Information Officer Carol Capas told Fox News Digital that the sheriff’s office was “in close contact” with Trump’s team.

Capas previously confirmed that 66-year-old Syrvud posted threatening messages on social media attacking Trump for two days.

Authorities say Syvrud has an outstanding warrant in Wisconsin for driving under the influence and failing to appear for driving under the influence. He also has an outstanding warrant in Graham County, Arizona, for hit-and-run and failing to register as a sex offender.

Trump’s visit to the swing state on Thursday had the theme “Make America Safe Again” and came as his opponent, Vice President Kamala Harris, was expected to deliver her speech at the Democratic National Convention.

Trump traveled to Pennsylvania, Michigan and North Carolina this week and will hold events in Las Vegas and the Phoenix suburb of Glendale on Friday.
