Trump is rolling over
He literally said the opposite though.
"I want to thank Emily Murphy at GSA for her steadfast dedication and loyalty to our Country. She has been harassed, threatened, and abused – and I do not want to see this happen to her, her family, or employees of GSA. Our case STRONGLY continues, we will keep up the good fight, and I believe we will prevail! Nevertheless, in the best interest of our Country, I am recommending that Emily and her team do what needs to be done with regard to initial protocols, and have told my team to do the same."
He told the GSA to go ahead as their lives were being threatened, and maintains that the case strongly continues in capital letters. That doesn't look like a concession to me. In the letter from Murphy at the GSA she is clear that Trump never even asked her to hold out, and that it was all her own doing.
So Trump never asked for her to delay the process, except in your own heads.
Trump posted that tweet to go ahead after she submitted that letter.
I know you want to spin this as a concession, because the left is desperate for some kind of concession, but it is not. Gore also got transition resources while legal proceedings were underway. Your fundamental mistake was to assume that Trump is a dictator mean man who was ever doing anything petty like telling her to hold out in an unprecedented and meaningless stand. He was not. That's all pure liberal fantasy.
