Approximately 280 people attended the online meeting. The attendees included children.Sen. Amy Sinclair, R-Allerton, stopped the meeting to say people who appeared without either a face or a name would be removed.”I will not tolerate pornography or hidden insults,” she said. “You will be removed from the subcommittee.”Iowa senators are holding all subcommittee meetings on bills virtually through Zoom this session as a precaution against the spreading coronavirus.
