How did members of President Reagan’s staff violate the Boland Amendment

They ignored it

Explanation:

The Boland Amendment aimed to prohibit the federal government from providing support to the Contras in Nicaragua. Instead of directly getting involved like that, they decided to ask someone else to support it, and that was Iran. Iran was the subject of an arms embargo which meant that the Contras were able to buy arms (guns) from Iran to overthrow the Nicaraguan government, and this ended up being a political scandal in Reagan's administration.
