There is only one thing he will do and only two outcomes. What he will do is the only thing he knows how to do and that is to be a asshole, When he testifies He will either answer with the truth and show the world what a total piece of shit he is or he will lie and go to jail for lying. Which he should be getting use to anyway because the got this pile of shit by the balls. This country can only gain by forcing this criminal to testify.
