Gen. Timothy D. Haugh, who was also the head of U.S. Cyber Command, was one of several national security officials fired on the advice of a conspiracy theorist.
President Trump has always solicited information from dubious sources. But now, in his second term, he has fewer people around him who try to keep those voices away.
No reason was given for the removal of Gen. Timothy D. Haugh. The far-right activist Laura Loomer had called for his ouster in a meeting with President Trump, an official said.
Gen. Timothy D. Haugh was appointed to his posts by President Joseph R. Biden Jr., a fact that caused the Trump administration to view him skeptically, former officials said.
