Chicago Chief Financial Officer Jennie Huang Bennett and Ald. Walter Burnett (27) speak during a Wednesday committee meeting.

Aldermen on Wednesday took several zaps at Mayor Lori Lightfoot’s proposal to give away $150 gas cards and $50 public transit cards, laying another bump in the road for her plan to help Chicagoans deal with rising fuel costs. The plan did not advance on Wednesday, putting its implementation in flux.
