"The letter’s admission to obstruction isn’t the first publicly documented evidence of obstruction. First, President Trump told both Russian officials and Lester Holt on NBC that he fired Comey because of Russia. Second, Comey testified that Trump asked him to “let go” of Flynn; later, a Trump tweet indicated he knew at that time that Flynn had committed crimes. Now we may have learned about a third admission this weekend: That the president tampered with witnesses in violation of obstruction statutes. With this letter’s admission added to the public evidence, we’re approaching a Watergate-level smoking gun on obstruction. Remember that there was never proof Nixon ordered the break-in. There was only proof of obstruction and interference with the investigation."
