Attorney General William Barr released his letter setting forth the principal conclusions relating to the Russia probe conducted by special counsel Robert Mueller.
Let's first be clear about what the letter does not say.
It does not say whether Mueller found a preponderance of evidence of crimes. (The criminal standard, beyond a reasonable doubt, is much higher.)
It does not say Mueller exonerated the president; to the contrary, it says the opposite. It does not say anything about possible financial crimes under investigation in the Southern District of New York.
It does not say why there were more than 100 contacts between the Trump presidential campaign and transition team and Russia-linked operatives, or why so many people denied that there were contacts.
