3) When either side yells about process, they’re holding a weak hand. Some Republicans have tried to distract from the was-there-collusion question by focusing on the leak of classified information regarding former National Security Adviser Michael Flynn’s conversation with the Russian ambassador. That’s a legitimate issue — and indeed, the only known crime committed so far — but it doesn’t get to the main issue of whether or not TrumpWorld colluded with Russians. Likewise, when Democrats yell about the methods House Intel Committee chairman Nunes employed to obtain evidence that might point toward Obama administration spying — that means they don’t want to talk about Obama administration spying.

4) Everyone should see the Nunes documents. In a smart — and belated — move Thursday, White House counsel Don McGahn invited the chairmen and ranking members of both House and Senate intelligence committees to come to the White House to view the documents Nunes saw. House Democratic Rep. Adam Schiff took McGahn up on it, but the Senate is making noise about demanding the documents be brought to the Senate. Enough with the turf battles; the investigation will be better off if both Senate Intel chairman Richard Burr and vice chairman Mark Warner go see the documents.

5) Mike Flynn’s request for immunity is no big deal. Of course the former national security adviser wants immunity; he’s under investigation by the FBI. But the public does not know exactly what Flynn is under investigation for. It is known that the Obama Justice Department used a possible violation of the never-successfully-prosecuted Logan Act as the reed-thin pretense for going to the White House with its concerns about Flynn talking to the Russian ambassador during the transition. It’s also known that there was nothing wrong with Flynn talking to the ambassador, even talking specifically about U.S. sanctions on Russia. What is not known is how the Flynn investigation might have spread into other areas — Turkey? — or whether it focuses on an alleged process crime like making a false statement to investigators. In any event, the House and Senate investigations can go forward without Flynn’s testimony.
