President Trump has suggested multiple times to senior Homeland Security and national security officials that they explore using nuclear bombs to stop hurricanes from hitting the United States, according to sources who have heard the president's private remarks and been briefed on a National Security Council memorandum that recorded those comments.

Behind the scenes: During one hurricane briefing at the White House, Trump said, "I got it. I got it. Why don't we nuke them?" according to one source who was there. "They start forming off the coast of Africa, as they're moving across the Atlantic, we drop a bomb inside the eye of the hurricane and it disrupts it. Why can't we do that?" the source added, paraphrasing the president's remarks.

  • Asked how the briefer reacted, the source recalled he said something to the effect of, "Sir, we'll look into that."
  • Trump replied by asking incredulously how many hurricanes the U.S. could handle and reiterating his suggestion that the government intervene before they make landfall. 
  • The briefer "was knocked back on his heels," the source in the room added. "You could hear a gnat fart in that meeting. People were astonished. After the meeting ended, we thought, 'What the f---? What do we do with this?'"

Trump also raised the idea in another conversation with a senior administration official. A 2017 NSC memo describes that second conversation, in which Trump asked whether the administration should bomb hurricanes to stop them from hitting the homeland. A source briefed on the NSC memo said it does not contain the word "nuclear"; it just says the president talked about bombing hurricanes.

  • The source added that this NSC memo captured "multiple topics, not just hurricanes. … It wasn't that somebody was so terrified of the bombing idea that they wrote it down. They just captured the president’s comments."
  • The sources said that Trump's "bomb the hurricanes" idea — which he floated early in the first year and a bit of his presidency before John Bolton took over as national security adviser — went nowhere and never entered a formal policy process.

White House response: A senior administration official said, "We don't comment on private discussions that the president may or may not have had with his national security team."

  • A different senior administration official, who has been briefed on the president's hurricane bombing suggestion, defended Trump's idea and said it was no cause for alarm. "His goal — to keep a catastrophic hurricane from hitting the mainland — is not bad," the official said. "His objective is not bad."
  • "What people near the president do is they say 'I love a president who asks questions like that, who’s willing to ask tough questions.' ... It takes strong people to respond to him in the right way when stuff like this comes up. For me, alarm bells weren't going off when I heard about it, but I did think somebody is going to use this to feed into 'the president is crazy' narrative."
  • Trump called this story "ridiculous" in a Monday tweet from the G7 summit. He added, "I never said this. Just more FAKE NEWS!"

The big picture: Trump didn't invent this idea. The notion that detonating a nuclear bomb over the eye of a hurricane could be used to counteract convection currents dates to the Eisenhower era, when it was floated by a government scientist.

  • The idea keeps resurfacing in the public even though scientists agree it won't work. The myth has been so persistent that the National Oceanic and Atmospheric Administration, the U.S. government agency that predicts changes in weather and the oceans, published an online fact sheet for the public under the heading "Tropical Cyclone Myths Page."
  • The page states: "Apart from the fact that this might not even alter the storm, this approach neglects the problem that the released radioactive fallout would fairly quickly move with the tradewinds to affect land areas and cause devastating environmental problems. Needless to say, this is not a good idea."

About 3 weeks after Trump's 2016 election, National Geographic published an article titled, "Nuking Hurricanes: The Surprising History of a Really Bad Idea." It found, among other problems, that:

  • Dropping a nuclear bomb into a hurricane would be banned under the terms of the Peaceful Nuclear Explosions Treaty between the U.S. and the former Soviet Union. So that could stave off any experiments, as long as the U.S. observes the terms of the treaty.

Atlantic hurricane season runs until Nov. 30.

Editor's note: This story has been updated to include President Trump's tweet responding to this story.

A federal judge on Tuesday temporarily blocked South Carolina's ban on mask mandates in schools, ruling that it discriminated against students with disabilities and violated the Americans with Disabilities Act.

Why it matters: As mask bans extend to public schools around the country, parents and disability rights activists have sounded alarm bells. The ruling may signal the outcomes of legal fights playing out across the country.

Florida Gov. Ron DeSantis took legal action on Tuesday to try to stop the Biden administration's immigration plans.

Why it matters: The Republican governor, who is running for re-election next year and is possibly eyeing a 2024 presidential bid, is picking a high-profile fight with Biden while re-upping his hardline stance on immigration.

Left: Senate's threat "insane"

Rep. Ro Khanna (D-Calif.) lambasted Sen. Kyrsten Sinema (D-Ariz.) on Tuesday, saying "it's insane" that "one senator" is blocking attempts to settle on a palatable figure for President Biden's proposed $3.5 trillion budget reconciliation package.

Why it matters: The figure is the linchpin to getting progressive support for the companion $1.2 trillion bipartisan infrastructure package. Khanna's statement reflects broader dissatisfaction among House progressives with Sinema and her fellow holdout, Sen. Joe Manchin (D-W.Va.).
