• Ronald Reagan. Reagan’s quest to fight communism suffered a setback in the middle of his first term when the Democratic Congress in 1983 passed the Boland Amendment, which restricted the CIA and the Defense Department from operating in Nicaragua. An even stronger version passed the following year. The Reagan administration diverted some of the proceeds of a secret arms sale to Iran to the anti-communist militia in Nicaragua known as the Contras, an action that directly violated the Boland Amendment.
Several top advisers to Reagan were implicated in what became known as the Iran-Contra affair. While the Reagan-appointed Tower Commission said Reagan's disengagement from White House management had made the diversion possible, Reagan himself was never formally linked to the violation of the Boland amendment.
