You can't be forced to testify against yourself so why is the donjohn getting himself deeper and deeper into troubled waters/quicksand? Is he that oblivious to cause and effect? Is his bubble world that tiny and airtight? He knows everything. Listens to no one. Reads nothing. And keeps tweeting tweeting tweeting tweeting. He is providing more and more rope which Mueller will gladly use to "hang" him metaphorically. There is something drastically wrong with a man who is so blind to what he is doing to himself. Oblivious. Strange.
