He’s the invisible man of Boston City Hall.

Councilor Ed Flynn – a thorn in the side of the Wu administration – is being canceled by the progressives running the city. He can’t get a bill passed, a hearing scheduled or even his photo removed from the lobby.

And in a new low, Council President Ruthzee Louijeune snubbed Flynn during this week’s State of the City festivities, accidentally, she claims, forgetting to introduce him when she announced all the rest of the city councilors.

It’s downright Stalinesque, like when the Soviets used to cut people out of photos.

The State of the City is a big deal to elected officials. It’s one of the few times councilors get to see their names mentioned on live TV without it following a story on corruption.

So when Louijeune did not utter Flynn’s name as she rattled off the names of all 11 of the other councilors, Flynn, a 24-year veteran of the U.S. Navy, was left quietly steaming.

It shows that the progressive regime led by Louijeune and Mayor Michelle Wu can be just as cutthroat as the old regimes that used to run City Hall.

Louijeune said in a statement to the Herald on Friday that she did not realize she “inadvertently omitted” Flynn’s name until after the speech.

“This was a complete mistake,” she said. “I have apologized to Councilor Flynn personally and acknowledged him in the ensuing social media posts. I want to express my respect and gratitude for Councilor Flynn’s service to the Boston City Council.”

It still seems curious that Louijeune couldn’t remember Flynn earlier this week.

Louijeune and Flynn, the son of former Mayor Ed Flynn and the leading conservative on the council, have clashed repeatedly in the chambers this year, with the president repeatedly shutting him down or ignoring his requests.

Flynn tried to pass a provision forming an ethics committee to oversee the council after corruption charges were filed against Councilor Tania Fernandes Anderson, and it was sent to die a quiet death.

Flynn also sent a letter to the Inspector General asking him to investigate the lack of transparency around Wu’s tax plan, and it was similarly shelved.

When Flynn wanted the Wu administration to appoint a “rat czar” to address the city’s massive rodent problem, it was also dismissed as a stunt by the administration.

And after Flynn asked Louijeune to remove his photo from the council lobby to protest his treatment, Louijeune dismissed him like a parent telling a toddler to be quiet.

Louijeune told the Boston Globe earlier this year that Flynn, who preceded her as council president, is trying to undermine her authority.

“He prefers to put things on letters and communications with me on X than actually speaking to me as a colleague,” she said. “Instead of being an elder statesman that councilors can turn to for advice and guidance, he instead wants to play the role of antagonist.”

Elder statesman? Even that sounds dismissive like Flynn is some doddering old man. He’s only 56. Louijeune is 38.

And Flynn is supposed to be an antagonist. Should he instead be like one of the other subservient councilors in Michelle Wu’s back pocket?

The people of South Boston and Chinatown who elected him want him to be a watchdog, not a lapdog.

When Louijeune took over as council president, City Hall observers wondered how she would treat the moderate to conservatives who used to be in charge. Now we know. It’s disrespectful to Flynn, a hard-working elected official whose family legacy has served the city well. He has his faults like most elected leaders, like sometimes being too much of a publicity hound.

City council presidents have very little authority under the city charter except to run the council meetings, appoint committee members and be acting mayor if the real mayor is not around. They’re no better than other councilors.

Flynn declined to comment for this column but you can be sure he noticed not being called at the State of the City.
