The case of death or disappearance of at least 10 top American scientists having information related to space, defense and life on other planets has surprised everyone. Due to which the Trump administration has ordered an investigation. Earlier this week, US President Donald Trump was briefed about the deaths and disappearances of prominent scientists.

According to American media, the first death occurred in July 2023. Michael David Hicks, a physicist at the NASA Jet Propulsion Laboratory, was an expert on cosmetics and steroids. He died on 30 July 2023. However, the cause of his death was not made public.

The hands of the people of China, Russia or Iran

Eric Burlison, a Republican MP from Missouri and a member of a committee of the House of Representatives, said that he has been drawing attention to the incidents of disappearance of some scientists for a long time. The MP argued that the incidents involving scientists were almost certainly linked to their access to classified aerospace, defense and UFO-related information and that China, Russia or Iran could be involved.

The MP told the TV program Fox & Friends whether this is just a coincidence, so we have to investigate it. We will have to ask our country's top investigators, FBI and every agency to investigate this matter.

Some scientists really disappear

Burlison said that some scientists literally disappeared without a trace. These include Air Force Major General William McClelland, who went missing in February. The MP claimed that McClelland had tried to contact him twice regarding his research on UFOs.

Disappearance of scientists is a serious matter

Trump described the incidents that happened with these scientists as a very serious matter and said that some of the scientists whose disappearance or death were reported were very important people. The President said that in the coming days he will get more information about these cases and whether there could be any connection between them.

Will investigate together with FBI

When Trump was asked on Thursday whether he thought there was any connection between the cases, he replied that he thought it was coincidental. White House Press Secretary Carolyn Leavitt said the administration is actively working with all relevant agencies and the FBI to review all cases and identify potential commonalities.

His statement said, no stone will be left unturned in this effort, and the White House will provide information as soon as it is available. He also said that the questions related to these matters are legitimate.
