Illinois' top leaders have gathered in Chicago's Polish neighborhood in honor of Pulaski Day.
Gov. Pat Quinn, Chicago Mayor Rahm Emanuel and Illinois Comptroller Judy Baar Topinka were among those scheduled to speak at the event Monday at The Polish American Museum.
Pulaski Day commemorates Casimir Pulaski, a cavalry officer born in Poland who fought in the Revolutionary War. It's an official holiday in Illinois on the first Monday in March.
Chicago city and Cook County offices are closed but state and federal offices are open. Chicago Public Schools are in session.
The Chicago area is home to one of the largest concentrations of people of Polish descent outside of Poland.
