A City Council bill being introduced Thursday would bar Mayor Adams’ office from unilaterally limiting the amount of space individual news outlets can take up in the City Hall press room — a move that has the potential to roll back a controversial media access policy implemented by the mayor’s team this summer. The bill, penned by Brooklyn Councilman Justin Brannan, would dictate that access to Room 9, the storied space where City Hall reporters work, cannot be altered unless such changes are “made with the joint approval of the mayor and the speaker of the Council,” according to a copy of the legislation provided to the Daily News ahead of its introduction. Brannan’s measure proposes that rule-making standard be retroactive from this past June 30 — the day before the mayor’s team imposed the new Room 9 policy. Under that policy, media outlets have only been allowed to use one desk each in Room 9. Before that policy, The News and other outlets with several reporters assigned to cover City Hall had multiple desks each in the room. brannanBarry Williams for New York Daily NewsThe bill was penned by Brooklyn Councilman Justin Brannan. (Barry Williams for New York Daily News) Adams and Fabien Levy, his spokesman, have said the new restrictions ensure community and ethnic media outlets are guaranteed space in Room 9 and that the policy actually expands press access. A spokesman for Council Speaker Adrienne Adams in June questioned that argument, saying that “as far as we know, Room 9 is not full and is available for use by any journalist who wishes to utilize it.” Should there be a need for more press access, the Adrienne Adams rep said at the time the Council was willing to work with the mayor’s side to find more space in the building. Speaking to The News this week, Brannan sided with the argument from the speaker’s office and noted his bill also requires that there be “adequate space” in Room 9 for working journalists and that “additional space” in City Hall can be designated for reporters as need be. He also confirmed that if his bill is adopted, the mayor’s Room 9 restrictions would need sign-off from the speaker, given the retroactive nature. “The administration doesn’t own City Hall or Room 9 — the people do,” Brannan said. Adams spokesman Fabien Levy said the mayor’s office will review Brannan’s bill “if and when it is introduced.” Levy also reiterated his argument that the new Room 9 policy is increasing press access: “More outlets and reporters are now able to cover their city government directly from City Hall, including outlets that have historically been left out of Room 9 that speak to diverse communities across the city.” Luiz C.

Ribeiro for NY Daily News) Adams, since taking office in 2022, has lamented what he sees as unfair coverage of his administration. On occasion, he has also criticized the lack of racial diversity in the City Hall press corps. The new Room 9 restrictions came after months of headlines about federal corruption investigations ensnaring his administration. Since then, federal prosecutors have indicted Adams on criminal charges alleging he solicited bribes and illegal campaign contributions from Turkish government operatives in exchange for political favors. He has pleaded not guilty and is dismissing calls for him to resign. In fighting the charges, Adams’ lawyer, Alex Spiro, has accused the feds of selectively leaking info to media outlets about their case against the mayor. Amid the legal troubles, more than a dozen top Adams advisers embroiled in the corruption probes have resigned in the past month.
