Edwards Substitute Amendment to Title II, HR 5052 regarding Nicaragua was passed in June 1986; it limited the Reagan Administration's use of $100,000,000 Congress had approved for military assistance to Contras seeking to overthrow the Sandinista National Liberation Front. Four amendments were proposed to put restrictions on the aid; in offering his, Mrazek raised concern that a Gulf of Tonkin type of incident could be exploited by the Reagan Administration to widen the course of the war, since the Contra camps were located along the border between Honduras and Nicaragua, and firefights between the Contras and the Sandanistas erupted regularly along the border. Mrazek argued that if American troops were killed in one of the camps, the Reagan Administration might send American forces into Nicaragua itself. Eventual declassification of secret White House memoranda revealed Mrazek’s concerns were justified. Of the four amendments being considered in the House of Representatives to put restrictions on the aid, the only one to win passage was the Mrazek amendment, which banned all U.S. personnel involved in training Contras from coming within of the Nicaraguan border.
