This comment from Stone says it all. Trump was scared of what he might say. I wonder what dirt Stone had on him.
@howardfineman: Just had a long talk with #RogerStone. He says he doesn’t want a pardon (which implies guilt) but a commutation, and says he thinks #Trump will give it to him. “He knows I was under enormous pressure to turn on him. It would have eased my situation considerably. But I didn’t.”
