Honest question, when was the money supposed to be spent? What date?

This is a good point that I've meant to mention....there is no federal law that prescribes an exact expedited timeline. Under the Impoundment Control Act of 1974 the President has the ability to go back to Congress with an official action/request to withhold such aid, and it's just common sense that there must be a period in which the President is considering whether to do that. The aid is necessarily in limbo during that period. Clearly Trump ultimately declined to take that action.
