I was joking about SES. They are over paid and hard (if not impossible) to fire and Obama used them, planted them, like moles. Pretty untouchable but i think I’ve seen prior another Trump EO that have changed that. I can’t see President Trump tolerating them a moment longer than legally required. :)
SESs are on a special pay scale and usually have to sign mobility agreements. For a lot of them, they usually have to attend an institution like the Atmy War College (at least in the DoD).
