I suggest you use the Internet and insert three terms into a Google search: pork, federal budget and earmark. You should get 4,480 hits, about one-third the number of items specified in the omnibus appropriation bill passed by Congress a few weeks ago. This is a topic requiring urgent attention because it is quickly ruining government operations and can bankrupt America.
An earmark (sometimes called a plus-up or add-on) is a specific appropriation that directs a federal agency to spend money in a certain way. It usually has characteristics of being requested by only one chamber in Congress, cover task not specifically authorized, is not competitively awarded, exceeds and was not requested in the President's budget, was not a subject of hearings and prior public record, and serves only special interests.
