Lionel Lebron, a YouTube conspiracy theorist who posed for a photo with President Trump in the Oval Office last year, claims that the federal government and military are manipulating the climate over the United States to sow chaos and disorder in society.

Dan Wigington of Geoengineering Watch joined Lebron on his YouTube podcast yesterday to discuss the government’s alleged routine of spraying chemicals into the sky in order to influence the climate in ways that shape world events and sow chaos into the American population. The duo specified that they wouldn’t call the chemicals sprayed in air “chemtrails” because the word “chemtrail” is too often associated with conspiracy theories. Rather, the duo opted to say that their theories are about “geoengineering.”

“Semantics are important and I don’t want to be an anti-semantic,” Lebron joked.

The science community has debated the ethics of using chemical agents to curb the effects of climate change, but the ideas are often considered to be far-fetched and too risky to attempt on a large scale. However, Lebron and Wigington pile conspiracy theories onto that scientific debate—theories about military forces using geoengineering to “topple nations” in “weather warfare,” and to destabilize society.

Wigington said that government agencies use chemicals sprayed in the sky to keep portions of the United States cooler than the rest of the planet so that it “confuses and divides the population as to the true state of the climate while the planet descends into total meltdown.”

“Not only is climate modification used for weather warfare, to topple nations without those nations ever knowing they were at war—nations in the Middle East and Africa and elsewhere that are forced to allow U.S. occupation. It’s used as a weapon of war, but also it’s used to confuse, divide, and thus pacify populations,” Wigington said.

Lebron agreed.

“Just like free radicals are so dangerous because they’re always trying to cleave and grab something, the worst thing that the military industrial complex, cabal, whoever you want to call these people—the asset-stripping jackals—the worst thing they could have happen is stability, calmness, power, strength, a sense of solemnity, purpose, cooperation. They don’t want that,” Lebron said. “Anything that makes them skeptical, that makes them run to the streets, run to the religions, run to their science—just run.”

Wigington went on to claim that weather forecasters are able to read scripts predicting the path of hurricanes because the government is using microwave beams and Raytheon military products to steer the aquatic cyclones.

Lebron is a QAnon conspiracy theorist who posed for a photo in the Oval Office with President Donald Trump last year. The Daily Beast reported that Lebron claimed to have taken the picture with Trump after he received a “special guided tour of the White House,” and that an Oval Office photo op with the president is something that would typically require a senior administration official’s blessing. Earlier this week, Lebron filmed an interview with actress Roseanne Barr, who is a QAnon believer.
