Is there anything, anything at all, that Trump could do that would lead to his fall?

In the opinion of Dylan Matt writing in Vox there is nothing that he could do or cause to be done that could dislodge him from office. The only thing that could bring him down is Paul Ryan working with Mitch McConnell and he does not believe that they would ever be inclined to do so no matter what Trump does.

I think he is correct. Trump could skewer journalists on the White House lawn with sharpened spikes ala Vlad the Impaler and they would excuse it and still not be inclined to go against him because doing so would bring their agenda to a crashing halt and vindicate what many in opposition have said about them.

But, what is your take? Is there anything that would be so repugnant that even his political allies Ryan and McConnell would disavow his actions and turn against him?
