COLUMBUS, Ohio — Masked anti-Israel demonstrators escalated their harassment of a Jewish congressman on the eve of Monday’s anniversary of the October 7 attack, pitching an encampment outside Ohio Democratic Representative Greg Landsman’s Cincinnati residence.

Landsman said Monday that the protesters arrived outside his home early Sunday. By evening, they set up tents, cots and sleeping bags in the road and spent the night harassing him and his family members, forcing them to secure a police escort in order to enter and exit safely, the congressman said.
