Kaploun claims a long standing relationship with Trump that was struck up while they both lived in New York, but his first recorded involvement with him was a 2018 demonstration of a water collecting technology from Israeli startup
Watergen, of which he was upper management, at
Mar-a-Lago. In 2020, he held a campaign event aimed at Jewish leaders for Trump that was attended by
Mike Pence. Kaploun was nominated as
U.S. special envoy to monitor and combat antisemitism by Donald Trump in May 2025. He has stated universities that tolerate "Jew-free zones" will face consequences. This statement is seemingly referencing now debunked stories appearing in conservative media stating that areas of Berkeley's campus had been marked as off limit to Jewish people during pro-Palestinian protests. == References ==
