The council created by retired Army Maj. Gen. John Singlaub was the U.S. chapter of the World Anti-Communist League, an international organization linked to former Nazi collaborators and ultra-right-wing death squads in Central America….

In the 1980s, McCain served on the advisory board to the U.S. chapter of an international group linked to ultra-right-wing death squads in Central America….

McCain has said he resigned from the council in 1984 and asked in 1986 to have his name removed from the group’s letterhead….

A news article and two documents tie McCain to the council in 1985, a year after he says he resigned. The group’s Internal Revenue Service filing in 1985, covering the previous year, lists McCain as a member of the council’s advisory board. In October 1985, a States News Service report placed McCain, Rep. Tom Loeffler, R-Texas, and an Arizona congressman at a Washington awards ceremony staged by the council.
