Reacting to the incident,  Rabbi Michael Barclay, who leads Temple Ner Simcha, posted on X: " Law enforcement has identified a suspect who was in an altercation with Paul Kessler immediately prior to his death. They are attempting to identify exactly what happened, as there is no video yet of the altercation. Witnesses range from it was verbal to him hitting Paul."

Ventura County Supervisor Jeff Gorell, whose district covers the location where the incident took place, said he as heartbroken by the incident.

"I’m heartbroken to hear of the tragic death of an elderly man today after having been struck at a protest in my district.  My prayers are with this man's family and friends.  Our whole community grieves at this senseless loss of life. I call for peace in our community," he said.

He said the investigation into the incident will be fair and thorough.

"I immediately reached out to local leaders at the Islamic Center of Conejo Valley & to our local Rabbis. I called for peace in our community.  Hate and violence are never the answer. We must have faith in the process.  There is an investigation. It will be fair and thorough," he wrote on X.
