"Anonymous," the so-called "senior official" in the Trump administration that was "part of the resistance" and wrote an anonymous opinion piece in the New York Times last year, said he would reveal his identity soon. The admission came during an Ask Me Anything (AMA) forum on Reddit, where the person answered questions from people curious about Anonymous' new book, "A Warning."

"As far as anonymity is concerned, I will not keep my identity shrouded in secrecy forever. I am not afraid to use my own name to express concern about the current occupant of the Oval Office," Anonymous said in a reply to a person wanting to know if and when the person behind the book would reveal his identity. "Donald Trump has not heard the last of me. There is more to come. Other people who are currently serving, and who have left, are also considering adding their voices before votes are cast in 2020. We talk about this with some regularity. In the meantime, Trump must answer to the American people for his own conduct instead of redirecting their attention."

Anonymous said he wrote the book so Trump supporters could get an "honest look" at Trump's actions.

"I wrote it as a wake-up call to Americans who, like me, hoped for the best when it came to the Trump Presidency and wanted him to succeed. I want them to see what I've seen firsthand, which is that the man has daily displayed his unfitness for office and, frankly, that he's a danger to the country," he wrote. "I don't make these comments lightly. But as public servants our oath is not to a man, it's to the Constitution."

Although Reddit administrators said they couldn't authenticate whether or not the person running the thread was the actual Anonymous source from the Trump administration, the author's publisher, Twelve Books, publicized the forum.

At the beginning of the month, the Department of Justice (DOJ) sent a letter to the publishing company, asking for information that would reveal whether or not Anonymous may have violated nondisclosure agreements "that are routinely required" in order to obtain access to classified information.
