S. 515 proposes the repeal of the Impoundment Control Act of 1974. This legislation, introduced by Mr. Lee in the Senate, seeks to eliminate the laws that restrict the President's ability to withhold or delay the spending of funds allocated by Congress.
Simple Explanation
S. 515 is a plan to change a rule that keeps the President from delaying or not spending money that Congress says should be spent. Without this rule, the President might be able to choose not to follow the spending decisions made by Congress.
