A committee of the House or Senate with legislative jurisdiction over laws that set up or continue the operations of Federal programs and provide the legal basis for making appropriations for those programs.
Legislation enacted by Congress that sets up or continues the operation of a Federal program or agency indefinitely or for a specific period of time. Authorizing legislation may limit the amount of budget authority which can be appropriated for a program or may authorize the appropriation of "such sums as are necessary."
A committee of the House or Senate that provides authority for Federal agencies to incur obligations and to make payments out of the Treasury for specified purposes. An appropriation act is the most common means of providing budget authority. Currently, there are 13 regular appropriations acts for each fiscal year. From time to time, Congress also enacts supplemental appropriations acts.
