The iran-contra affair involved the use of profits from iranian arms sales to support the contras was a scandal during the reagan presidency was not uncovered until the clinton presidency improved détente with the soviet union

The correct answer is involved the use of profits from Iranian arms sales to support the Contras

It was a scandal during Regan but the biggest problem was that it sold weapons to Iran which was on an arms embargo which the US didn't care about. The funds gotten were used to fund Contra fighters in Nicaragua which was also problematic.
