(contrary to feigned ignorance from the 'cognitive genius'). That is until she:

1. got full enough of herself to make HERSELF the star, upstaging Trump, and

2. when caught with her fingers in the cookie jar, she pointed those grubby little fingers right back AT him.

She got all of her brand new planes (3) and he didn't, plus her antics and grifting were drawing attention towards her, and away from him, and he can't have THAT............She also had her constant companion, Boy Toy....while cucking her husband.......Something Trump can't do out in the open to Melanoma......................

Brainless Barbie Bondi is next up for De-Throning.........all of these idiots in his CABAL are soooo stupid thinking that it won't happen to them........a prime example was his first disposable asset, Sarah Huckapig...............it's open season, it's NOW...
what have you done for me today..........

He doesn’t want them talking about their time at DHS. It’s a payoff. Neither of them will be doing a single thing at their new “job”.

24x7...and LOTs of overtime.

that the only position she's good at is missionary.

She knows too much, or at least Trump thinks she does.

...like everything else.

First of all, he's never cared what a woman says about him. It is too easy for him to dismiss whatever she might say--even with receipts. When have receipts even actually mattered for him?

And Corey is far too much of a leech for power to ever go against him.

This is about HIS ego. It is face-saving for him to move her into this made-up position and quietly put her out to pasture (pun intended.)

At this point his ego is all that really matters IMO.

He knows that there is nothing he can do today that will really get him in trouble. The things he really worries about are all in the past. So unless she has video of that; it's all about him.....

of a Narcissistic Psychopath.........

AND A TWPC........Teenie Weenie Peenie Complex............

She's made him look bad.

Everybody knew she was a bad choice.
He nominated her anyway.
Flat out firing her would be admitting a mistake, and he won't do that.
I think it simpler to suggest he "transferred" her to preserve his own ego.

But replaces her with a man. He knew she’d fail and that’s not a problem for him, just her. Maybe she knows too much or he’s protecting himself.

Certainly, he doesn't care about her, but he'd never admit he made a mistake.
I think it's just that simple.
Besides, what corruption would that dimwitted know about that isn't being done in plain sight.

He’s not frightened of what she might say. He could snap his fingers and have her murdered on top of a rock pile if he wanted to and the republicans would continue to do nothing.

It was all about being able to say he never makes mistakes.
