Now it makes sense (found on FB)

The SC US Marshal is a Biden appointee. Trump wanted 2 things from McMaster.

Redistricting and the US Marshal gone.

When asked to bring up redistricting, the Senate said no and went on break. (was it a staged?) Trump leaned on McMaster a bit then they made a deal. Endorse Evette and I'll get them back. Trump endorsed her and they came back.

McMaster had a side deal with Evette, I will get you a Trump endorsement if you choose my son as Lt Gov. She did/will

Onto the US Marshal. He is a Biden appointee and Trump wanted him OUT! His scheduled replacement was kicked to the curb. McMaster's head of security and driver was soon going to be out of a job. McMaster told Trump that he will help him as long as he names his guy as SC Us Marshal.

The part to be seen... Will Trump offer her an Ambassadorship to get her out of SC, making room for McMaster's son to become governor?

Gotta keep the grift going.
