More than two dozen Senate Democrats want the Federal Communications Commission to check if it's been invaded by robots before voting to undo its net neutrality rule this month.
The FCC voted last month to take down the Obama-era net neutrality rule, which was aimed at preventing companies from interfering with the flow of information online from their competitors.
But Democrats, led by Sen. Maggie Hassan, D-N.H., said they're worried that the FCC's decision might have been influenced by robot commenters that don't reflect what real people think about it.
"In fact, there is good reason to believe that the record may be replete with fake or fraudulent comments, suggesting that your proposal is fundamentally flawed," they wrote.
"To this end, we request a thorough investigation by the FCC into reports that bots may have interfered with this proceeding by filing hundreds of thousands of comments," they added.
Democrats said the FCC ignored 50,000 other consumer complaints that aren't in the public record, and said that imbalance means the FCC "cannot conduct a thorough and fair evaluation of the public's views on this topic."
They added that New York Attorney General Eric Schneiderman has been looking into the "fraudulent comments," and thinks "hundreds of thousands" of comments the FCC received may have violated state law by impersonating New Yorkers.
"[W]e are requesting that you delay your planned vote on this item until you can conduct a thorough review of the state of the record and provide Congress with greater assurance of its accuracy and completeness," the Democrats wrote.
The FCC is set to vote Dec. 14 to repeal the net neutrality rules.
