“He was clearly hoping that this could be built into a “Trump’s fault” narrative”
No, looking at his social media, he just hated Jewish people.
Apparently, to him, Jewish people are bad because they took him in, gave him productive employment, and paid for his expensive private college, and that made him feel bad about himself.
The guy was also a Democrat operative. He was probably out to make this Trump's fault.
Likely a two birds with one stone thingy. He hates Trump and Jews.
