Trump Tells U.N. ‘Your Countries Are Going to Hell’

Donald Trump was a key speaker at the United Nations’ General Assembly on Tuesday, Sept. 23, and immediately sparked buzz for his remarks on immigration.

The U.S. president opened his address by criticizing the United Nations itself, complaining about their faulty teleprompter and a broken escalator that he encountered during his visit.

“What is the point of the United Nations? You do nothing to support the end of war, other than write a pathetic letter or two, which does nothing,” he said of the assembly, which is convening for its 80th session this year. “Empty words don’t solve wars… A bad escalator and a bad teleprompter is all I got from the United Nations.”

Turning the topic to immigration, Trump, 79, also took his fellow world leaders to task, insisting it was “time to end the failed experiment of open borders.”

“I’m really good at this stuff,” he declared. “Your countries are going to hell.”

The president then pressed European leaders in particular, claiming they were only allowing immigrants into their countries “to be nice.”

“You want to be politically correct, and you’re destroying your heritage,” he said. “If you don’t stop people that you’ve never seen before, that you have nothing in common with, your country is going to fail.”

“I’m the president of the United States, but I worry about Europe. I love Europe, I love the people of Europe. And I hate to see it being devastated by energy and immigration, that double-tailed monster that destroys everything in its wake.”

Of his administration’s immigration crackdown, Trump boasted, “Once we started detaining and deporting everyone who crossed the border — and removing illegal aliens from the United States — they simply stopped coming.”

Trump also criticized his fellow leaders for buying into the “green scam” of global warming, calling it “the greatest con job ever perpetrated on the world, in my opinion.”

Despite significant evidence to the contrary, the U.S. president said predictions about global warming causing a “global catastrophe” were wrong and “made by stupid people,” adding, “If you don’t get away from this green scam, your country is going to fail.”

The U.N. speech continued a week of bold claims by the president. On Monday, Sept. 22, he held a press conference with Health and Human Services Secretary Robert F. Kennedy Jr., during which they said that prenatal exposure to acetaminophen, the generic name for Tylenol, “can be associated with a very increased risk of autism.”

The relationship between acetaminophen and autism has been the subject of many research studies, but most have delivered inconclusive results. Acetaminophen has long been considered one of the few safe options to treat pain or fever during pregnancy.

“People have been taking Tylenol since 1960, and there’s a very long history of safety here,” Dr. Karam Radwan, director of the UChicago Medicine Neurodevelopmental Clinic, told PEOPLE.

A spokesperson for Tylenol’s parent company, Kenvue, released a statement to PEOPLE, saying, “We believe independent, sound science clearly shows that taking acetaminophen does not cause autism. We strongly disagree with any suggestion otherwise and are deeply concerned with the health risk this poses for expectant mothers.
