The Chicago tribune is a daily newspaper which begin publication on June 10, 1847. In the 1850s, under the editorship of Joseph Medill, the Tribune became associated with Abraham Lincoln and the newly-formed Republican Party. Colonel Robert R. McCormick, Medill's grandson, took control of the paper in the 1920s, and ran the paper until his death in 1955. Under him, the Tribune took a firmly conservative and anti-New Deal stance. In 1974 the Tribune was the first newspaper to publish the complete text of the Watergate tapes. In 2008, the Tribune for the first time endorsed a member of the Democratic Party for President of the United States: Barack Obama.
