Some supporters of the QAnon conspiracy gathered in Dallas this week as a theory circulated that John F. Kennedy Jr., who has been dead for more than 20 years, would reappear and announce that former President Trump will be reinstated as president. Kennedy, the son of former President John F. Kennedy, died in 1999 in a plane crash at the age of 38. But some believers of the QAnon conspiracy theory say that Kennedy did not die, and he is set to return as Trump’s vice president, according to multiple reports.
