Yes, Ted Gunderson, former FBI agent, has been talking about it for decades, pity he's no longer here to see it come out.
From Wikipedia…
"He also investigated a child molestation trial in Manhattan Beach, California. In a 1995 conference in Dallas, Gunderson warned about the supposed proliferation of secret occultist groups, and the danger posed by the New World Order, an alleged shadow government that would be controlling the United States government."
