You know... if you're going to be so willfully ignorant that you ignore the realities of politics today, you should at least use the correct word.
Acquit mean he was found not guilty. This can be due to insufficient evidence/not meeting the threshold for legal guilt (or in this case, sufficient politicians not possessing a spine).
Exonerate indicates more than he was proven innocent (not the same thing as acquitted, and not what happened here). Also, I believe someone is exonerated only after they are found guilty and that decision is later reversed.
