Like some legal zombie that can’t be killed, the argument that “collusion is not a crime” is back and walks among us. And it’s still nonsense.

There were reports last week that former Trump attorney Michael Cohen would testify, contrary to repeated White House denials, that President Trump knew of and approved the infamous Trump Tower meeting in June 2016, when Donald Trump Jr., Jared Kushner and other campaign officials met with Russians offering damaging information about Hillary Clinton.

Faced with this new evidence of what looks remarkably like colluding with the Russians, the president’s defense has returned to the claim that any such collusion, even if it happened, would not be a crime. On “Fox and Friends,” Trump attorney Rudolph W. Giuliani recently said, “I have been sitting here looking in the federal code trying to find collusion as a crime. Collusion is not a crime.” The president himself picked up on the theme, tweeting: “Collusion is not a crime, but that doesn’t matter because there was No Collusion (except by Crooked Hillary and the Democrats)!”
