The Boston firefighters union has chosen not to endorse Ruthzee Louijeune in this year’s at-large City Council race, after backing her initial bid for office.

Sam Dillon, president of the Boston Fire Fighters Local 718, said Louijeune actively sought the endorsement, but did not receive the vote of the union’s membership at a Thursday night meeting.

“The way that we approach endorsements is we stand with those who stand with us,” Dillon told the Herald Friday. “Our goal is to encourage political candidates and elected officials who are going to support and advance the causes of Boston firefighters and our families.”

He added, however, that, “Our membership’s decision to not endorse Councilor Louijeune, I don’t think should be taken as an indication that we believe that’s not her. It’s a democratic process and our membership rendered a vote.”

Louijeune was among the councilors who voted for a city budget that would have cut millions from municipal departments, including Boston Fire, that provide direct services to residents. Mayor Michelle Wu vetoed the cuts.

Dillion declined to comment on whether the lack of endorsement was based on a specific vote taken by Louijeune, or a policy decision she’s made since joining the City Council in January 2022.

She was backed by the 1,500-member union in the 2021 election cycle, with the union writing on its Facebook page, “Ruthzee has the passion and conviction to meet the urgency of this difficult moment and lead us to a better Boston.”

Louijeune did not respond to a request for comment.

The union chose to endorse Councilor Erin Murphy and challenger Bridget Nee-Walsh in the at-large City Council race. Both were endorsed two years ago, Dillon said.

While endorsements were made ahead of the Sept. 12 preliminary, they’ll have no bearing for that particular race until the November election. Since there are only eight candidates running for an at-large seat, no primary is needed.

The union chose to make endorsements in just four other races: City Council President Ed Flynn, who is running unopposed in District 2; John Fitzgerald for District 3; Jose Ruiz for District 5; and William King for District 6, Dillon said.

Flynn and Murphy were the only two incumbents endorsed. District 3 Councilor Frank Baker is not seeking reelection, but challengers were selected over sitting District 5 and 6 Councilors Ricardo Arroyo and Kendra Lara.

Dillon said the recent controversies on the City Council, some of which involved Arroyo and Lara, had no bearing on the endorsement process.

“We don’t solicit endorsements,” he said. “It comes down to whoever approaches the union looking for an endorsement.”
