In an interview this week, Mr. Hawley said that he was concerned that tech companies had too much sway over regulatory discussions and criticized Mr. Schumer’s decision to hold the A.I. meeting behind closed doors.
“This is the biggest gathering of monopolists since the Gilded Age and I’m disappointed it isn’t happening in public and not in a real hearing,” he said.
Senator Mike Rounds, Republican of South Dakota, who will help moderate the forum, said the executives were critical to Congress’s education.
“What we don’t want to do is regulate from a point of not having good information in the first place,” he said at a Washington Post event on Tuesday.
Labor union leaders and civil society groups have complained about the tech industry’s rush to roll out new products that may threaten jobs or steal intellectual property, and that have upended education.
“Workers are tired of being guinea pigs in an A.I. live experiment,” said Liz Shuler, the president of the A.F.L.-C.I.O. union, who will be at the meeting. “The labor movement knows A.I. can empower workers and increase prosperity, but only if workers are centered in its creation and the rules that govern it.”
