At the same time that the American government was considering their options on selling arms to Iran, Contra militants based in Honduras were waging a guerrilla war to topple the Sandinista National Liberation Front (FSLN) revolutionary government of Nicaragua. Almost from the time he took office in 1981, a major goal of the Reagan administration was the overthrow of the left-wing Sandinista government in Nicaragua and to support the Contra rebels. The Reagan administration’s policy towards Nicaragua produced a major clash between the executive and legislative arms as Congress sought to limit, if not curb altogether, the ability of the White House to support the Contras. Direct U.S. funding of the Contras insurgency was made illegal through the Boland Amendment, the name given to three U.S. legislative amendments between 1982 and 1984 aimed at limiting U.S. government assistance to Contra militants. Funding ran out for the Contras by July 1984 and in October a total ban was placed in effect. The second Boland amendment, in effect from 3 October 1984 to 3 December 1985, stated:
During the fiscal year 1985 no funds available to the Central Intelligence Agency, the Department of Defense or any other agency or entity of the United States involved in intelligence activities may be obligated or expended for the purpose of or which may have the effect of supporting directly or indirectly military or paramilitary operations in Nicaragua by any nation, organization, group, movement, or individual.
In violation of the Boland Amendment, senior officials of the Reagan administration continued to secretly arm and train the Contras and provide arms to Iran, an operation they called “the Enterprise”. As the Contras were heavily dependent upon U.S. military and financial support, the second Boland amendment threatened to break the Contra movement and led to President Reagan in 1984 to order the National Security Council (NSC) to “keep the Contras together ‘body and soul'”, no matter what Congress voted for.
A major legal debate at the center of the Iran–Contra affair concerned the question of whether the NSC was one of the “any other agency or entity of the United States involved in intelligence activities” covered by the Boland amendment. The Reagan administration argued it was not, and many in Congress argued that it was. The majority of constitutional scholars have asserted the NSC did indeed fall within the purview of the second Boland amendment, though the amendment did not mention the NSC by name. The broader constitutional question at stake was the power of Congress vs. the power of the presidency. The Reagan administration argued that because the constitution assigned the right to conduct foreign policy to the executive, its efforts to overthrow the government of Nicaragua were a presidential prerogative that Congress had no right to try to halt via the Boland amendments. By contrast congressional leaders argued that the constitution had assigned Congress control of the budget, and Congress had every right to use that power not to fund projects like attempting to overthrow the government of Nicaragua that they disapproved of. As part of the effort to circumvent the Boland amendment, the NSC established “the Enterprise”, an arms-smuggling network headed by a retired U.S. Air Force officer turned arms dealer Richard Secord that supplied arms to the Contras. It was ostensibly a private sector operation, but in fact was controlled by the NSC. To fund “the Enterprise”, the Reagan administration was constantly on the look-out for funds that came from outside the U.S. government in order not to explicitly violate the letter of the Boland amendment, though the efforts to find alternative funding for the Contras violated the spirit of the Boland amendment. Ironically, military aid to the Contras was reinstated with Congressional consent in October 1986, a month before the scandal broke.
