The unseen driver followed Arndt's car into the gas station parking lot. A child could be heard in that car earlier in the video.

Mequon police said the interaction resulted from alleged dangerous driving, but that was not captured on the video.

He refused to say what happened on the road to prompt the interaction or his anger. "All I'm going to say," Arndt said, "is I could have used a better choice of words. But my stance on Israel stays."

He told us, "I am not anti-anyone. I am anti-Israel. I am anti-Zionists."

Following someone and filming them after the road rage incident is a kind of escalation, right? Not great optics, but this was not some random interaction it seems.
