Mayor Brandon Johnson’s floor leader and zoning committee chair Ald. Carlos Ramirez-Rosa (35) threatened to hold up zoning decisions in the wards of alderpeople who attended a meeting last week where alderpeople were supposed to vote on a proposal that would ask Chicago voters in the spring whether the city should remain a sanctuary city, alderpeople said on Monday. 

In a Monday statement announcing his resignation from his position as floor leader and zoning committee chair, Ramirez-Rosa apologized to Ald. Emma Mitts (37) “for the disrespectful interaction outside of Council Chambers.” Ramirez-Rosa also apologized to Ald. Nicole Lee (11), Ald. Chris Taliaferro (29) and Ald. Felix Cardona (31), who he said he heard "felt disrespected and harmed by my actions.”
