I think he wants her out of the senate. Remember, she did say she could handle that 3 am call better than he could. He is going to put her to the test. If she doesn’t pass his “pay scale”, he will probably can her!
BINGO! He wants her where he can control her and where she can't undermine him. This will get her out of the Senate. Next step will be to devise a situation where she fails, then he cans her. Then she's out there with nothing to do but make speeches and bake cookies.
I will be very surprised if she takes the bait.
