A panel event Saturday featuring some of most prominent black conservatives in the nation was interrupted when vulgar protesters piped into its Zoom livestream and spewed cuss words before one man exposed himself masturbating.

The video of the event shows it went smoothly for the first 90 minutes, but then someone can be heard chanting over the audio then yelling “shut the f*ck up you fa**ot,” and “f*ck you” repeatedly. At one point it sounds like a female voice can also be heard, but it’s unclear.

The vulgarities continued until “a man exposed himself on the event’s Zoom link and began masturbating before organizers could shut down the feed,” News Talk 1130 reported.
