"So I call on my colleagues to halt this vote until we get to the bottom of what has happened with these stolen identities and the quality of our public record", said Rosenworcel, who was nominated by President Barack Obama to the FCC.
"The idea that the FTC will come to the rescue if net neutrality is destroyed at the FCC is a bad joke".
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.
The FCC's commenting system is not like an election. "This is just evidence that supporters of heavy-handed Internet regulations are becoming more desperate by the day as their effort to defeat Chairman Pai's plan to restore Internet freedom has stalled", Pai's office said in a statement. "Save American jobs by repealing Net Neutrality", the comment, which used the staffer's name and childhood address in Rhode Island, said.
"At today's news conference, they didn't identify a single comment relied upon in the draft order as being questionable".
The other Democratic FCC commissioner, Mignon Clyburn, is calling attention to consumer complaints against ISPs over net neutrality.
As Republicans now hold a majority of the FCC's five seats, the order to repeal the net neutrality rules is expected to pass. Twenty-eight U.S. senators have asked that the vote be postponed due to the allegations of fraud dismissed by Chairman Pai.
The FCC is set to repeal net neutrality in a vote on December 14th, but its comment period - which is meant to give the public a voice in the process - has been beset with problems.
The senators are concerned that the agency's public comment record on the issue may have been tampered with.
Pai's office has not returned SiliconBeat's repeated requests for comment Monday.
A report commissioned by Broadband for America, which is backed by major telecommunications companies including AT&T and Comcast, found that the vast majority of personalized or unique comments - that is, the comments least likely to have been faked - were in favor of the current net neutrality rules. The AG said a man in Albany even reported that his dead mother made a comment. "No vote should take place until a responsible investigation is complete".
Citing the findings of Schneiderman's office and other researchers, the senators wrote, "These reports raise serious concerns as to whether the record the FCC is now relying on has been tampered with and merits the full attention of, and investigation by, the FCC before votes on this item are cast".
According to Schneiderman, the net neutrality feedback process generated more than 23 million total comments, marking an unprecedented level of participation.
