My two takeaways, with the second being worse than the first:
1. He did a good job throwing gasoline onto the impeachment fire... essentially saying that we couldn't charge Trump with any crimes at all because of the DoJ position on indictment of a sitting President.... the way to handle this is via Congress (since it isn't by federal prosecution)...
2. By again overemphasizing unproven claims about Russian interference, he is solidifying the JUSTIFICATION defense for Comey, McCabe, Clapper, Brennan, Lynch, Yates, and the entire crew...
