David Sacks and Bo Hines were disappointing hires from the get go. Neither had expertise in the domain, both heavily promoted shitcoins before entering White House. But their time in the White House was always limited to 130 days as SGE, so I'm not mad they left, just frustrated they accomplished nothing while they were here.
Cynthia Lummis is 71 years old and does not want to serve another 6 year senate term. Nothing odd or unusual there. Honestly commendable knowing when to hang up the hat.
Robert Malone is a health professional working for CDC. I don't know why you included him on the list. The job he resigned from had no policy overlap with BTC.
