with concern over PAC influence in Congress. In 2009, there were 4,600 business, labor and special-interest PACs including ones for lawyers, electricians, and real estate brokers. From 2007 to 2008, 175 members of Congress received "half or more of their campaign cash" from PACs. From 1970 to 2009, the House expanded delegates, along with their powers and privileges representing U.S. citizens in non-state areas, beginning with representation on committees for Puerto Rico's resident commissioner in 1970. In 1971, a delegate for the District of Columbia was authorized, and in 1972 new delegate positions were established for U.S. Virgin Islands and Guam. 1978 saw an additional delegate for American Samoa, and another for the Commonwealth of the Northern Mariana Islands began in 2009.

Others saw pressure to squeeze a political position into a thirty-second soundbite. A report characterized Congress in 2013 as unproductive, gridlocked, and "setting records for futility". In October 2013, with Congress unable to compromise, the government was shut down for several weeks and risked a serious default on debt payments, causing 60% of the public to say they would "fire every member of Congress" including their own representative. One report suggested Congress posed the "biggest risk to the U.S. economy" because of its brinksmanship, "down-to-the-wire budget and debt crises" and "indiscriminate spending cuts", resulting in slowed economic activity and keeping up to two million people unemployed. There has been increasing public dissatisfaction with Congress, with extremely low approval ratings which dropped
