There is now a Times of Israel article as of less than an hour ago that mentions his relationship to Meir Kahane briefly. And this, so far the most thorough piece https://www.trtworld.com/us-and-canada/extremist-rabbi-tries-to-run-over-pro-palestine-protesters-in-ny-18075898
Honestly it's unreal that no major networks are covering. This is a HUGE story. Meir Kahane's groups have been on terrorist lists in the US & Israel & internationally for decades. For good reason. See the details in Wikipedia @Wikipedia to start.
