INDIANAPOLIS (AP) — A virtual meeting of the Indiana Election Commission on an online video platform was disrupted with pornographic imagery on Friday.

Commission chairman Paul Okeson said the meeting was open to anyone to join. By law, meetings of government agencies must be accessible to the public. Okeson said the interruption on the Zoom video conferencing site was swiftly taken care of.

An unidentified participant took over a single screen shared among commission members, state and county election officials and used it to display a video of a man performing a solitary sexual act. The video ran for about one minute before the manager of the commission’s online services removed it.

“That was sufficiently disturbing,” Okeson said after the image was removed.

The FBI in March issued a warning about the interruption of Zoom meetings after several incidents at schools in the Boston area. Officials have advised Zoom meetings not be made public.
