When I watched that clip of him waving at the crowd I thought well good for him he's on his way back to the White House only to be slapped silly when it was mentioned he went right back into the hospital after the publicity stunt he just pulled.
See, that's what a guy would do whose mind is defective, abnormal, desperate for sympathy, desperate for approval, desperate for adulation and respect so badly that he will try to acquire it any and every way he can think of, mostly due to the fact that his lifestyle, the lifestyle of opulence and excess is now at imminent risk due to his own self-induced failings and malfeasance.
His character is that of a tyrannical child born into excessive wealth who was taught that it was perfectly OK to be that way because everyone owed him whatever it is his insecurities demanded leveraged by all that wealth that he could dump into his attorney's pockets to force things to go his way, if not on a temporary basis.
Problem being, it's all finally being caught up with him. What he put on hold via lawsuits, high risk loans and threats is coming back at him with a vengeance and there's nowhere to run and hide anymore.
