An Arizona man has been fired from his job after allegedly threatening anti-Trump protesters planning a rally in Phoenix to coincide with President Trump's speech Tuesday night.

"You are all pathetic," James Cobo wrote on the "Protest Trump Downtown Phoenix" Facebook event page. "Cant [sic] wait to drive through. 4x4 with push bumper will be sweet in this crowd. I named my lifted truck 'trumper.'"

Members of the Facebook page contacted Cobo's employer, West Valley Tires Point S, calling for his dismissal, according to the Arizona Republic.

"West Valley Tires Point S wants to publicly state we do not condone or support violence or prejudice in anyway shape or form," the business wrote on Facebook on Wednesday. "We were recently made aware of an employee that posted outrageous posts and videos that are in no way affiliated with the positive views, values and appreciation we have for people in our community and throughout the world."

Cobo was "no longer affiliated with West Valley Tires Point S," the statement continued.

Cobo's posted threat follows the death of 32-year-old Heather Heyer, who was killed earlier in August when James Fields allegedly drove a car into a crowd protesting a "Unite the Right" rally in Charlottesville, Va.

Cobo told the newspaper the post was "a tasteless joke." He did not apologize for the offense he had caused nor express any sympathy for Heyer's death.

"I don't care that I got fired. I already got another job," he said. "The only thing that upsets me about this situation is that adults are able to throw a tantrum and raise hell and get what they want by doing so. This is not how America is supposed to work."
