Washington (CNN) Donald Trump is fond of reminding you -- well, everyone really -- that he is making history all the damn time.

"Nobody's done what I've done, and what this administration has done in the first two years, and we're not even that close to two years," Trump told Fox News' Harris Faulkner last week.

In at least one respect, Trump is 100% right! What is it, you ask? The record number of senior people leaving his administration!

(OK, that last exclamation point was, admittedly, gratuitous.)

According to the indispensable Kathryn Dunn Tenpas at Brookings , 65% -- 65%!!!! -- of Trump's senior staffers and Cabinet officials have left the administration over the course of the past two-ish years.
