Iranian minister for the Revolutionary Guards aligned with Prime Minister Mousavi who sought to open a second arms-sales channel to Iran.

Ari Ben-Menashe is an Iranian-born Israeli-Canadian who describes himself as a former military-intelligence official and became a recurring source for claims about U.S.-Israeli arms dealing, the October Surprise, PROMIS, Robert Maxwell, and Jeffrey Epstein, claims repeatedly found uncorroborated and, by a congressional task force, not credible.

Ayatollah Ruhollah Khomeini was the Shia cleric who led Iran's 1979 Islamic Revolution, overthrew Shah Mohammad Reza Pahlavi, and served as the Islamic Republic's first Supreme Leader until his death in 1989; his government's hostage-taking and arms dealings made him a central figure in the Iran-Contra and October Surprise controversies.

Gary Sick was the principal White House aide for Iran on the Carter National Security Council during the 1979-1981 hostage crisis, and subsequently authored October Surprise (1991), the book that launched congressional investigations into allegations that Reagan's campaign secretly negotiated with Iran to delay the hostages' release.

Lee Hamilton served as a Democratic congressman from Indiana from 1965 to 1999 and co-chaired both the House October Surprise Task Force (1992-1993) and the 9/11 Commission (2002-2004); his decision to decline a three-month extension of the October Surprise investigation, despite new evidence arriving in the final weeks, has been cited as a significant limitation on that inquiry.
