The fallout from last week’s shocking election of Liz Breadon as Boston City Council president continued Monday, with two councilors initially passing on serving as Breadon’s vice president, and further concerns voiced over backroom deals.

Breadon, an ally of Mayor Michelle Wu, released her committee chair assignments late Monday, with chairmanships of the most important committees going to other Wu allies who backed her in her last-minute bid for the presidency.

“As Boston continues to change, the Boston City Council must evolve with it,” Breadon said in a statement. “These committee assignments reflect a commitment to clearer oversight and stronger collaboration.”

Gabriela Coletta Zapata, who claimed to have the presidency locked down for months but ultimately dropped out a day before the vote after three of her key supporters flipped on her, has accepted Breadon’s offer to be the Council vice president, per Breadon’s office.

Coletta Zapata had initially passed on the position over the weekend, according to Breadon, who told an NBC10 reporter that she rejected the vice presidency offer to become chair of the powerful government operations committee, which is responsible for finalizing legislation proposed by the mayor and City Council.

Despite that report, final committee assignments from Breadon’s office show that Coletta Zapata will serve as both Council vice president and chair of the government operations committee, which she also chaired last term.

Coletta Zapata did not respond to the Herald’s request for comment.

Brian Worrell was the second councilor to reject Breadon’s offer to be her vice president on Sunday, after Coletta Zapata passed on it and he was offered the post.

“I was proud to serve the body as their vice president last term, and similar to my colleague from District 1, I am respectfully declining the opportunity to be the vice president for this upcoming term,” Worrell told the Herald late Sunday night.

“I’m looking forward to working in other committees and just gaining more experience in different committees where my work, my passion and my interests are really aligned,” he added.

Worrell was vying for the Council presidency for months. He appeared to have the election clinched after Coletta Zapata dropped out, until Breadon was prodded to pursue the presidency by Sharon Durkan and Enrique Pepén, two close allies of the mayor who Breadon said visited her house “quite late” on Sunday night to urge her to consider to run as a “compromise candidate.”

Former City Councilor Tania Fernandes Anderson, who resigned in early July after being convicted on federal corruption charges, wrote a letter to her supporters last week that detailed allegations of tumultuous behind-the-scenes maneuvering by Wu and her Council allies that upended Worrell’s bid for the presidency.

Breadon tasked Worrell with chairing the environmental justice resiliency and parks committee along with the committee on labor and economic development, which has absorbed the former committee on small business and professional licensure.

Last term, Worrell chaired the Ways and Means committee, which oversees the Council budget process.

Ways and Means and Government Operations are seen as the top two committees, and are key prizes during Council presidency negotiations.

This term, Ways and Means will be chaired by Councilor Benjamin Weber, a Wu ally who nominated Breadon for Council president at the Jan. 5 Council meeting, when she was elected by a 7-6 vote.

Allies of the mayor who voted for Breadon will also chair other key committees.

Henry Santana will serve another term as chair of the Public Safety and Criminal Justice committee; Durkan will head planning, development and transportation; and Pepén will chair housing and community development.

John FitzGerald, who, per sources was at one time in line for Ways and Means chair, will instead continue as Public Health, Homelessness and Recovery chair.

FitzGerald was one of the three councilors to flip from Coletta Zapata to Worrell, and voted for Worrell for president.

Flynn, a Wu critic who nominated Worrell, was assigned to chair city services.

Julia Mejia arguably received the most favorable committee chairmanship of Worrell’s supporters, with education.

Erin Murphy, a Wu critic and Worrell supporter, will continue to serve as chair of human services, which was known as strong women, families and communities last term.

Ruthzee Louijeune, the Council president last term who opted to vote for Breadon rather than support her former vice president, will chair two committees including census, redistricting and elections, which was established by Breadon this term.

Breadon said over the weekend that she was planning to release her committee assignments on Monday, but didn’t do so until late in the evening — leading to uncertainty and frustration throughout the day from some of her colleagues, who raised concerns about her leadership capabilities.

Given the way her last-minute election over Worrell, a Black man, unfolded, Flynn and Murphy called for Breadon to reconsider her vice presidency pick, and select a councilor of color as her deputy rather than Coletta Zapata.

Flynn told the Herald “the Council is off to a rocky start,” and emphasized the need to be “transparent with the public and with all city councilors, even those that did not vote for the Council president.”

“This has not been a clear or confidence-building start to the term,” Murphy said in a statement to the Herald. “I do have concerns about what this says about the Council’s ability to govern. How we handle pressure, honor commitments, and conduct ourselves in moments of consequence matters.

“The way this process played out raises real questions about whether power was prioritized over the institution, and whether unity and stability were put second to last-minute maneuvering.”

Murphy said it was her hope that the Council president “selects a person of color to serve alongside her, especially after a highly qualified Black councilor who had earned broad support was ultimately blocked from the presidency.”

“I have always taken this job seriously,” Murphy said. “I respect the responsibility voters entrusted to us, and I believe this body functions best when adults in the room lead with integrity, transparency, and respect for process. That is the standard I will continue to hold myself to, and it is the standard I will continue to expect from this Council.”
