The FCC is scheduled to hold a vote on December 14th over an order to replace and repeal the 2015 rules enforcing net neutrality.
Schneiderman, a Democrat who has been a longtime nemesis of Republican President Donald Trump, said his office first contacted the FCC in June for records "related to its public comment system that were necessary to investigate which bad actor or actors were behind the misconduct", he said in his open letter to Pai.
Schneiderman says his office requested the actual comments records from the FCC numerous times but so far the FCC has not complied.
He added that at least one million more comments came from real people whose identities were stolen.
Last week, Schneiderman's office unveiled an online tool that helped people see if their names had been used without their knowledge on comments submitted to the FCC.
FCC Commissioner Jessica Rosenworcel, a Democrat appointed by President Obama who supports keeping the current regulations, said that almost a half-million comments before the FCC were filed from Russian email addresses, and that 50,000 consumer complaints are missing from the record.
"Without additional information about the alleged anomalies surrounding the public record, the FCC can not conduct a thorough and fair evaluation of the public's views on this topic, and should not move forward with a vote", Hassan and 27 other senators - including Sens.
The protests are being organized by Team Internet, a "grassroots network of almost half a million volunteer activists spearheaded by Demand Progress, Fight for the Future, and Free Press Action Fund, three of the groups behind the massive July 12 net neutrality day of action that drove millions of comments, emails, and phone calls to the FCC and Congress".
After learning that Schneiderman meant to hold a press conference on Monday afternoon alongside FCC Commissioner Jessica Rosenworcel, the FCC Office of Inspector General reportedly contacted the NY attorney general by email and offered its assistance with the investigation. There are multiple reports that the comments include fake ones, perhaps made by bots.
The spokesperson said that Schneiderman had not identified as fake any comments that were used as part of Pai's proposal.
Internet service providers now have to maintain equal access to all users of the internet.
The FCC is set to vote December 14 whether to scrap Obama-era rules around open internet access that prevent phone and cable companies from favoring certain websites and apps.
Rosenworcel said the public comment procedure is important to the agency's process, and it should not make any decision without a guarantee that the responses are genuine.
"The FCC needs to help with state investigations". The integrity of our process is at stake.
