• QAnon followers had believed that a group of "deep state" elites would be arrested in October.

A QAnon supporter wrote an open letter to Donald Trump expressing frustration that the movement's conspiracy theories kept failing to happen.

Donny Warren's letter, which Insider reviewed, appeared on the Telegram channel of the prominent QAnon adherent Ron Watkins on Sunday. It was first reported by Newsweek.

Followers of the far-right group believe, baselessly, that a "deep state" cabal of Satan-worshipping pedophiles are embedded in institutions including the Democratic Party and are responsible for nefarious acts. They also believe that Trump was elected as part of a plot to secretly fight that cabal.

In his letter, Warren complained that "Red October" — one of the multiple dates on which leading QAnon proponents promised the alleged cabal members would be rounded up and arrested — had not come to pass.

"At the beginning of October, we were told of a Red October, with rumors of mass arrests across the world," Warren wrote.

"We were given hints by 'Q' experts that November was to be THE month," he wrote. "I told a few of my awake friends that either this would be the best Thanksgiving ever, or the worst. Guess which one it was?"

"Awake" is often used to describe other adherents of the QAnon movement and alludes to "The Great Awakening," an event in January when Trump was supposed to declare martial law and imprison his political enemies, which also did not happen.

"For months, I have anticipated each day with excitement knowing that I was watching my president and his crew of Patriots take back our country and our freedom. I am losing that excitement now," Warren said. "This is starting to get very old."

Warren also described the toll that his belief in the conspiracy theory was taking on his family. "They think I am a nut for believing in all this," he said.

The letter was addressed to Trump, his former national security advisor Michael Flynn, Russian President Vladimir Putin, Chinese President Xi Jinping, and John F. Kennedy Jr., "if he is alive."

Hundreds of QAnon supporters gathered in Dallas earlier in November in the belief that Kennedy Jr., who died in 1999, would reappear and announce that he wasn't dead.
