Chicago, Illinois (CNN) -- The first black woman to win a seat in the U.S. Senate has thrown her political hat back into the ring, beating Monday's deadline for hopeful candidates to turn in the required signatures needed to be placed on the mayoral ballot here.
"I just want to serve," Carol Moseley Braun said Saturday as she announced her intent to run for mayor of Chicago before a crowd of supporters.
The former senator joins a crowded field of major contenders, including former White House Chief of Staff Rahm Emanuel.
Each one hopes to replace retiring Mayor Richard Daley, who has presided over the city for more than 20 years.
Moseley Braun made history when she was elected in 1992 as the first black woman in the U.S. Senate. In 1998, she lost a re-election bid, and was later named U.S. Ambassador to New Zealand.
The 63-year-old also has some experience in Illinois government; before winning the 1992 Senate race for the seat President Barack Obama went on to hold, she served as a state senator.
