"Barbara Jordan 1976-04-07" by Thomas J. O'Halloran, U.S. News & World Report Magazine - U.S. Library of Congress, U.S. News & World Report Collection 
Texas Representative Barbara Jordan was the first African-American woman elected to congress from a former Confederate state. A member of the House Judiciary Committee she delivered an impassioned speech prior to the committee voting to impeach Nixon. An impeachment vote was never taken in the full House because Nixon resigned on August 9th, 1974.
Jordan's speech is a short, but powerful statement on the constitution and abuse of power.
