Some of Mayor Brandon Johnson’s former colleagues on the Cook County Board of Commissioners told The Daily Line they hope that collaboration between the county government and City Hall increases on myriad issues under the fledgling administration. 

Johnson, who served just over one full term as the county commissioner for District 1, became the city’s 57th mayor Monday morning during a lively ceremony attended by many of his former board colleagues.
