What was the scandalous crime deal with Iran?

The scandalous crime involving Iran typically refers to the Iran-Contra Affair, which occurred during the 1980s. In this political scandal, senior U.S. officials secretly facilitated the sale of arms to Iran, which was then in conflict with Iraq and designated as a state sponsor of terrorism. The profits from these sales were then used to fund Contra rebels in Nicaragua, circumventing a congressional ban on such funding. The affair raised significant ethical and legal questions about the conduct of the Reagan administration.
