Bolton said that threat “remains today,” pointing to an Iranian plot to assassinate Trump before the 2024 election.

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 executive order targets the clearances of 50 people in all, including the 49 surviving signatories of the letter.

Bolton departed the first Trump admin in 2019 and has continued to require Secret Service protection due to threats from Iran.

President Trump issued 46 executive orders on his first day in office targeting national security issues, including the removal of any security clearances held by 51 former intelligence officials linked to election interference in the 2020 presidential campaign.

John Bolton, who left the Trump White House in November 2019, has had Secret Service protection during the Biden administration due to concerns that Iran could target him.

"I am disappointed but not surprised that President Trump has decided to terminate the protection previously provided by the United States Secret Service," John Bolton said.

President Joseph R. Biden Jr. had granted Bolton and another Trump national security adviser protection in 2021 after threats from Iran.

The executive order targets the clearances of 50 people in all, including the 49 surviving signatories of the letter.

The Trump administration removed former national security adviser John Bolton's Secret Service protection. The decision was made in the past 24 hours, sources said.

In revoking John Bolton's Secret Service detail, President Donald Trump has shown a petty disregard for the First Amendment and Iran's assassination threats.
