Congress.gov is a valuable tool for advocates interested in federal legislation. It is the official website for federal legislation provided by the Library of Congress. The website provides full information about federal bills including the text of bills, actions taken, amendments and co-sponsors. By viewing whether their elected officials have sponsored a bill, advocates can determine appropriate messaging when contacting them. Congress.gov also allows advocates to sign up to get alerts when any changes occur to a bill, such as new co-sponsors.
