Generally people have the wrong idea how congress decides to spend money. The budget gets compiled by the various executive agencies. It essentially lists their required spending needs based on the authorizing legislation they are working under. As such the budget is more akin to an audit than anything else. Congress doesn't decide how much money to spend and on what as part of the budget process. That actually comes from the authorizing legislation that is passed separately.
