A second presidential memorandum targeted Miles Taylor, who was a top official at the Department of Homeland Security during Trump’s first term and anonymously wrote a 2019 book criticizing the then-president. Taylor made his identity public in October 2020.

“I think it’s a very important case, and I think he’s guilty of treason, if you want to know the truth, but we’ll find out,” said Trump as he signed the order on Taylor.

In response, Taylor said via text message: “I said this would happen. Dissent isn’t unlawful. It certainly isn’t treasonous. America is headed down a dark path.”

Krebs had questioned Trump’s claims of election fraud in the 2020 presidential election in which he lost to Democrat Joe Biden.

The order signed on Wednesday called for a review of Krebs’ activities as a government employee, including his leadership of the Cybersecurity and Infrastructure Security Agency, a White House fact sheet said.
