It’s not unusual for politicians to have minders.
Keeping the crazies out of the White House was Javanka’s job, which is why they set up office in the West Wing and fired all the MAGA people the day Trump moved in.
Their absence at Mar-A-Lago is noted.
I do believe that Trump didn’t know who Fuentes was. You pretty much have to spend a lot of time on social media to have ever heard of the guy.
