Regarding why folks go to work at the White House: they desire power, they want to build their resume by taking a relatively low paying government job so they can cash in post-WH employment. This applies no matter the POTUS. Like you stated in another post, they know what they are signing up for.
As for Pompeo, he is put there to be the inside man for the globalist agenda, the Agenda 21 folks. He's a yes man to them. And his other job is supposed to be throttling Trump (good luck).
What exactly that has not already been explored and tried to make stick are you all proposing to impeach and remove him from office FOR? I get he disgusts the left, I get that he can be a bully, but what actions has he committed that rise to the level of reversing the people's will by electing him? Oh, and "knowing what you signed up for when you decided to do it"....if it comes down to trying to remove him from office, I predict the silent majority will not sit still and allow that.
