Jordan should be in jail or at least out of office in disgrace.
However using the dollar sign merely indicates that the person in question cares only about money. I have mostly seen it used in the name Microsoft to ridicule various unpopular decisions they have made or their monopoly accusations back in the day.
And who Jordan is really criticizing here is Nadler, suggesting he is motivated by Steyer's money. So I guess it can be considered antisemitism on the definition that includes whenever someone who happens to be Jewish is called greedy.
