There will soon be a new mayor of Chicago. Incumbent Democrat Lori Lightfoot conceded Tuesday in her bid for re-election. She said she congratulated Brandon Johnson and Paul Vallas, who are on a collision course to meet in a runoff election on April 4th. Johnson is a county board commissioner and Vallas is a former public schools executive. Lightfoot became the first Black woman to be elected mayor of Chicago back in 2019.
