To the American's surprise and disappointment, after Carter made his promise, President Banisadr added additional demands: official American approval of resolution of the hostage question by Iran's parliament (which would leave the hostages in Tehran for another month or two), and a promise by Carter to refrain from making ``hostile statements''. Carter also agreed to these demands, but again Khomeini vetoed the plan. At this point President Banisadr announced he was ``washing his hands of the hostage mess''.
