What Reagan administration policy did the Iran-Contra affair violate?

The Iran-Contra affair violated the Reagan administration's official policy of not negotiating with terrorists, as it involved secret arms sales to Iran, which was then considered a state sponsor of terrorism. Additionally, it contravened the Boland Amendment, which prohibited the use of U.S. funds to support Nicaraguan Contra rebels fighting the Sandinista government. This covert operation undermined congressional authority and raised significant legal and ethical questions about executive power.
