"In 1997, Congress passed the Balanced Budget Act, a bipartisan effort to cut back on spending. The act put a cap on the number of annual residencies CMS would support, and froze the funding at 1996 levels. . . . Since 2007, a bill to increase the number of residencies has been introduced in every Congress . . . but never passed."
