The 21st alderman joins a growing list of City Council members who won't be running for re-election.
"For the 19 years that I have served alderman of the 21st ward, I have walked in the footsteps of my father and I took pride in modeling servant leadership for our beautiful communities," said Alderman Brookins. "I am thankful for having the trust of my community as we worked together to provide greater economic opportunity and prosperity for our people."
