We can only conclude the following three possibilities from this item:
1. Trump has not learned his lesson and continues to surround himself with those who would sabotage and undermine his professed plans to do his part in saving and preserving our nation and making it great again. Why he would continue to do this, no one knows.
2. Trump is willing to forgive those who are willing to make peace with him and cooperate with him. McCarthy had deemed the election results legitimate, blamed Trump for the J6 storming of the Capitol building, and had considered having Trump censured for his alleged involvement in the so-called riot but decided against. It should be very clear now that Trump had nothing to do with the storming of the Capitol. He never once incited his supporters to riot or to take the Capitol by force. He had actually planned to lead his supporters in a peaceful demonstration to the Capitol but the alleged riot had begun before Trump even finished his J6 speech addressing the election fraud.
McCarthy also seems to understand that fighting against Trump may not be in his political best interests and therefore might rather cooperate with Trump than be an obstacle to him.
3. It is possible Trump may have some damning information on McCarthy unknown to us that could possibly end his political career or worse, even have him subject to investigation and possibly indicted and thrown in prison. McCarthy probably knows this too and therefore may have decided that if push comes to shove, the only option for him in this case is to go along to get along.
