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.

The order required developers of AI systems posing risks to national security, the economy, public health or safety to share the safety test results.

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.

Migrants allowed into the U.S. temporarily under certain Biden administration programs can be quickly expelled, according to a memo sent by the Trump administration's acting secretary of homeland security.

The acting head of the Department of Homeland Security (DHS) is allowing immigration enforcement agents to swiftly deport those who came to the U.S. under multiple pathways established under the Biden administration.
