Donald Trump veered into a rambling and decidedly not-so-festive tangent during a White House Christmas reception on Sunday, during which he predicted what his eldest son, Donald Trump Jr., will do after he “kicks the bucket.”

According to the president, his son won’t stick around very long to mourn.

Trump was recounting a story about how White House physician Dr. James Jones, who was in attendance, had once survived a life-threatening viper bite while hiking in the Peruvian jungle with former President Barack Obama’s daughters, when the monologue took a dark turn.

Trump acknowledged it was “a terrible Christmas story” to tell, but said it was “a hell of a” one anyway as he weaved in complaints about how environmentalists might want to save the snake, made a separate dig about sharks, a longtime Trump nemesis, and praised the looks of a woman who he believed looked like his daughter, Ivanka Trump.

Claiming to be “fascinated” by wildlife stories, Trump said his remarks about Jones’ ordeal, which the physician detailed in his memoir “Venom And Valor,” were meant to back up his theory that “Wildlife always wins.”

“I’m saying this for my son, by the way,” Trump said. “Because I have a son who would rather be in the jungle than any place on Earth.”

Then came the prediction about Trump Jr., whose hunting antics have drawn much scrutiny and criticism before, and who has long been rumored to be a potential heir to his father’s political MAGA movement.

“When I kick the bucket someday, I figure — I think he’ll be here for about two days,” the president suggested. “He’ll go and pay his respects, and we’ll say, ‘Where’s Don?’ He’d rather be in some jungle, or some… and he’s a really good hunter. But remember this: wildlife always wins, unfortunately, in this case.”
