President Donald Trump signed an executive order Monday revoking the security clearance of 51 former intelligence officials who signed a 2020 letter arguing that emails from a laptop belonging to Hunter Biden carried “all the classic earmarks of a Russian information operation” and that of his former national security adviser John Bolton.

Biden's order required developers of AI systems that pose risks to U.S. national security, the economy, public health or safety to share the results of safety tests with the U.S. government, in line with the Defense Production Act, before they were released to the public.

President Trump took executive action Monday to start revoking the security clearances of his former national security adviser, John Bolton, and dozens of intelligence officials who signed a letter in 2020 claiming emails found on a laptop owned by Hunter Biden bore the hallmarks of a Russian disinformation campaign.
