For too many years, the practice of congressional earmarking continued virtually unabated. During the 10-year period that ended in 2005, according to the Congressional Research Service, the number of earmarks skyrocketed, increasing by more than 400 percent and reaching a level of more than 16,000. This increase was particularly troubling because all too often, earmarks are an easy vehicle for special interest deal-making – inserted into congressional spending bills without filter for merit, need, priority, or any scrutiny by the public, the media, or other members of Congress.
