2 U.S.C. § 168d — Authorization of appropriations for Constitution Annotated

This section authorizes Congress to appropriate money to carry out sections 168 through 168d of this title — the sections covering the printing and distribution of the Constitution Annotated and its supplements. The law does not set a specific dollar amount. It authorizes "such sums... as may be necessary," meaning Congress can appropriate whatever amount is needed. Once appropriated, that money remains available until it is fully spent — it does not expire at the end of a fiscal year.
