April 13 (Reuters) - A Texas man ‌was charged ​with hurling ​a Molotov cocktail nL4N40T1GB at the home of OpenAI CEO Sam Altman and attempting to set fire to the AI ‌firm's headquarters.

Daniel Moreno-Gama, 20, was captured on surveillance video throwing an ⁠incendiary device outside Altman's San Francisco residence, according to a Federal Bureau of Investigation affidavit ‌filed in federal court on ‌Monday.

They said Moreno-Gama was carrying a self-authored "anti-AI" document when the San Francisco Police Department arrested him.

According to the FBI, the document Moreno-Gama wrote - which ​was cited as evidence of motive - contained threats directed at Altman.

"We are only at the beginning of this investigation, but if the evidence ⁠shows that Mr. Moreno-Gama executed these attacks to change public policy or to coerce government and other ​officials, we will treat this as an act of domestic terrorism and together with our law enforcement partners prosecute him ​to the fullest extent allowed by law," U.S. ‌Attorney Craig Missakian said in a statement.

OpenAI faces growing scrutiny for its role in national security, including criticism of ⁠a proposed deal with the U.S. government to allow its artificial intelligence technology to be used in classified military operations.

Moreno-Gama is charged with attempted damage and destruction of ⁠property by means of explosives and possession of an unregistered firearm.

Police said he traveled from ​Texas to California before carrying out the attacks and they recovered multiple incendiary devices, kerosene and a lighter at the time of his arrest.

Moreno-Gama told security personnel at the ‌company's headquarters that he intended to burn the building and harm the people inside, according to court records.

If convicted, ‌he faces a mandatory minimum sentence of five years and up to 20 ⁠years in prison on the ‌explosives charge, and up to ​10 years in prison on the unregistered firearm charge, court filings showed.
