In 1950, Sen. Joseph McCarthy (R-WI) held up a piece of paper in Wheeling, West Virginia and said it was a list of 205 Communists within the US State Department. The paper was blank, there was no list. McCarthy used that lie to wage a four year reign of terror on America.
The evil secret society trope is shopworn but effective.
