President Donald Trump has his sights set on a pair of officials who worked in his first administration, whom he believes committed “treason.”

On Wednesday the president signed two executive actions in which he order investigations of former senior Department of Homeland Security official Miles Taylor, and the former head of the Cybersecurity and Infrastructure Security Agency (CISA), Chris Krebs respectively.

In the order both men were also stripped of their security clearances.

Taylor was made famous when he published op-ed pieces in The New York Times under the nom de plume “Anonymous,” which also served as the title of his book that was published later.

“Miles Taylor was entrusted with the solemn responsibility of Federal service, but instead prioritized his own ambition, personal notoriety, and monetary gain over fidelity to his constitutional oath,” the memo from the president said.

“While serving as an administrative staff assistant at the Department of Homeland Security, Taylor stoked dissension by manufacturing sensationalist reports on the existence of a supposed ‘resistance’ within the Federal Government that ‘vowed’ to undermine and render ineffective a sitting President,” the memo said.

“He illegally published classified conversations to sell his book under the pseudonym ‘Anonymous,’ which is full of falsehoods and fabricated stories,” it said.

“I further direct the Attorney General and the Secretary of Homeland Security, in consultation with any other agency head, to take all appropriate action to review Krebs’ activities as a Government employee, including his leadership of CISA. This review should identify any instances where Krebs’ conduct appears to have been contrary to suitability standards for Federal employees, involved the unauthorized dissemination of classified information, or contrary to the purposes and policies identified in Executive Order 14149 of January 20, 2025 (Restoring Freedom of Speech and Ending Federal Censorship),” the president said in the memo.

“As part of that review, I direct a comprehensive evaluation of all of CISA’s activities over the last 6 years, focusing specifically on any instances where CISA’s conduct appears to have been contrary to the purposes and policies identified in Executive Order 14149. Upon completing these reviews, the Attorney General and the Secretary of Homeland Security shall prepare a joint report to be submitted to the President, through the Counsel to the President, with recommendations for appropriate remedial or preventative actions to be taken to fulfill the purposes and policies of Executive Order 14149,” he said.
