Eric Trump says prez saw Charlie Kirk as ‘second son’ — and calls assassination ‘the biggest mistake’ for left

Eric Trump said Tuesday that his dad, President Trump, saw Charlie Kirk as “a second son” — making his assassination “the biggest mistake” that will hurt the left for “generations.”

Kirk had known the Trumps for at least a decade after first pitching his organization, Turning Point USA, which twice helped reach younger voters and twice propel Trump into the White House, Eric Trump told “Fox and Friends” early Tuesday.

Kirk’s movement became “exactly what he described to me 10 years ago when he became obviously dear friends with [President Trump],” the president’s son said.

“He became … probably a second son to my father,” Eric said.

“He fought beside us. I was on that stage with him a hundred times. I mean, he was an amazing person.”

Kirk, 31, was shot dead last week while speaking at a campus event at Utah State University.

It followed two attempts on Trump’s life before the 2024 election — once when he was hit in the ear at a rally in Butler, Pa., and again when he was targeted during a golf outing in West Palm Beach, Fla.

Eric Trump blamed all three shocking events on left-wing extreists, one he predicted will hurt Trump’s opponents for generations.

“I always talk about the law of unintended consequences in the world, and they made the biggest mistake of their life,” Eric Trump said. “They tried to do it to my father in Butler, they tried to do it to him on a golf course — now they did it to Charlie,” he said.

“And you have the law of unintended consequences and they wonder why… we won every swing state. They wonder why we won the popular vote. They wonder why they just lost an entire generation — who, by the way, is going to be voting for generations.

“It’s all because of the insanity that no one can get behind,” he said.

The law of unintended consequences refers to the unforeseen effects rippling from a purposeful action.

Since Kirk’s death, Turning Point USA has been flooded with more than 37,000 new chapter requests, which would increase TPUSA’s presence on college and high school campuses by nearly twentyfold, the nonprofit announced Monday.
