The 17-member Cook County Board of Commissioners was sworn into office during a special meeting Monday morning. The board features four new faces and one fewer Republican commissioner. 

Board President Toni Preckwinkle took her oath of office shortly thereafter to be sworn in for a fourth term as the county’s top executive. Preckwinkle’s reelection set her up to be the longest serving board president since George Dunne, who served from 1969 to 1990. Preckwinkle took office in 2010.
