This is not an April Fool's joke.

Jimmy Kimmel’s show aired a “death threat” against Donald Trump made by Texas Sen. Ted Cruz, a Trump staffer charged on CNN today.

Jimmy Kimmel To Ted Cruz: “If he wasn’t Ted Cruz, he probably would be reported and investigated by the Secret Service,” Karen Giorno, identified by CNN as Trump campaign southeast regional director, told Jake Tapper.

“It should offend every American. This is a presidential race,” said the staffer of a GOP candidate who, two months earlier, boasted at a rally, “I could stand in the middle of 5th Avenue and shoot somebody and I wouldn’t lose voters.”

“This is not a time to be joking about the front-runner and essentially running him over and causing him harm or death,” Giorno continued.

Last night, Cruz made his first visit to Kimmel’s ABC late-night show.

He followed a guest who had showed viewers how to scare a pal on April Fools Day by taping a photo of Donald Trump to the back of the pal’s car, covering the back-up camera.

Said Cruz, when Kimmel asked if he liked President Obama or Trump better, “If I were in my car and getting ready to reverse, and saw Donald in the backup camera, I’m not confident which pedal I’d push.”

Cruz communications director Alice Stewart told Tapper, “It was a joke, on a late-night comedy show,” adding it was “no surprise the Trump team is going to focus on this.”

CNN contributor and GOP strategist Ana Navarro counseled Giorno that the country will not get through this election cycle that Trump has done so much to plunge into a “cuckoo crazy” phase without the help of humor and liquor, “so lighten up.”
