Current U.S. Senators for the state of Illinois:
Illinois was admitted to the Union on December 3, 1818. Senators from Illinois are elected to Class 2 and Class 3.
Of the eight African Americans ever to sit in the U.S. Senate since Reconstruction, three have held Illinois's Class 3 seat, including Barack Obama who went on to become the President of the United States. This makes Illinois the state with the most African-American senators. Illinois's current U.S. senators are Democrats Dick Durbin (serving since 1997) and Tammy Duckworth (serving since 2017).
