The House Committee on Appropriations is responsible for legislation allocating federal funds prior to expenditure from the treasury. Appropriations are generally limited to the levels set by the Budget Resolution drafted by the House Committee on the Budget. The Committee is also responsible for supplemental spending bills, which are sometimes needed in the middle of a fiscal year to compensate for emergency expenses. source
