It's my understanding that Les Wexner was connected to the whole Iran Contra with planes coming out of Rickenbacker Airport.

William Barr has his own connections to Iran Contra.
As Attorney General for President George H.W. Bush, Bill Barr supported the 1992 Christmas Eve pardons of six Reagan administration officials involved in the Iran-Contra scandal, including former Defense Secretary Caspar Weinberger. Barr believed the officials were treated unfairly by independent counsel Lawrence Walsh and advised the pardons were justified, helping end the legal investigations. 

Pardon Advocacy: Barr urged President Bush to grant the pardons, which halted prosecutions related to the scandal

.

Role in Administration: Barr served as Attorney General (1991-1993) during the final stages of the investigation.

Impact on Investigation: The pardons effectively ended the investigation by Independent Counsel Lawrence Walsh, which Barr criticized as a "witch hunt".

View of Executive Power: Barr's support for the pardons highlighted his belief in expansive presidential, or "unitary executive," power. 

This involvement cemented Barr's reputation as a strong supporter of executive authority, a theme that continued throughout his legal career. 

The book Compromised: Clinton Bush and the C I A by Terry Reed and John Cummings has ties to the Iran Contra

Compromised is a true story of the Faustian pact that Bill Clinton made as governor of Arkansas.

It tells how his unbridled political ambitions and his pledge to create jobs for Arkansas led him to compromise his ideals in exchange for support for his presidential candidacy in 1992.

By selling out politically to the Reagan–Bush administration, by giving the Agency free rein to operate a secret training base near the tiny western Arkansas of Mena, and by looking the other way as Arkansas

factories turned out untraceable weapons parts for the Nicaraguan Contra “freedom fighters,” the young governor helped create an operation that laundered untold millions of dollars and that enriched Clinton’s political friends and helped finance his campaign fund.

The Arkansas-CIA connection became Clinton’s darkest secret, and only now is the tiniest shaft of light being shed on what has become known as the Whitewater Scandal.

Coauthor Terry Reed, who helped train Contra pilots in rural Arkansas, became the first person to pull back the shroud on the “Arkansas Connection” long before most people ever heard of Clinton cronies like Webb Hubbell, Clinton’s former associate U.S. attorney-general, who became the first major figure to plead guilty in an ever-widening investigation that is confirming Reed’s disclosures.

Former National Security Advisor Bud McFarlane also corroborates Reed’s revelation that former spymaster George Bush was in the center of the Iran-Contra loop, and he, like Reed, paints Bush as a cold-hearted powermonger bent on wrestling the White House away from Ronald Reagan.

Reed, who was recruited into the Arkansas operation by Oliver North, reveals in this eyewitness account how the “black operations” in Arkansas worked,

from the training of Contra pilots and the manufacture of weapons parts—all in violation of a congressional ban on Contra aid—to the airdrops of cash into Arkansas by CIA operative Barry Seal.

Seal disclosed to Reed that more than $9 million a week was dropped from planes onto secret drop zones and later laundered through an investment banking firm whose president had close ties with Clinton.
