You seem keen on implying this is limited to "the current administration's staff", but that's just what we happen to have data on. Unless proven otherwise, it's reasonable to assume this over-representation is the rule, not the exception that applies only to the current admin's staff.
To support this, see my other comment showing the Federal Reserve chair and political donors exhibit the same over-representation (the donor data is recent, but the Fed chair is since 1970, so it's unlikely this is a new thing that suddenly came out of nowhere): https://news.ycombinator.com/item?id=37465220
It's not limited to the staff either - of the 26 cabinet positions (including president and vice president) in the Biden White House, 7 are held by Jews (2.4% of US population), and just 6 by gentile Whites (55% of US). One of those 6 is Joe Biden himself, and all 3 of his children married Jews. Sources:

So this prevalence is an aberration compared to the base rate in the population, and therefore this aberration should be presumed to be the norm? Interesting approach.
