Guilty of what? Being a jerkass? We already knew that and voted for him anyway.
Guilty of What:
1. Cohen testified that Trump had advanced warning of the WikiLeaks dumps, and the contents of those dumps, which is receiving stolen goods, since the emails were stolen.
2. Trump conspired with Russian to subvert the US elections;
3. Trump lied to the American people about his business and personal connections to Russian oligarchs, and Saudi Arabian oil sheiks. Lying about facts material to his election is illegal.
4. Trump committed campaign finance violations paying off Stormy Daniels to hush her up in the wake of the Access Hollywood tape.
5. More campaign finance violations, involving the National Enquirer and Karen McDougall.
Yesterday, Michael Cohen's testimony contained so many smoking guns on all of the above, that there is no question that Democrats must impeach him and soon, for the good of the country.
