40, so far.

I don't know if this is the usual number or not...

Only 5 who were registered as lobbyists in the last year though.

Out of 500+ appointees? Honestly I would have guessed a much higher number than the 5 or the 40.

I'm guessing a decade or two ago it would have been a much larger number.
