is the crime, not "collusion". Two people have to agree to commit the crime and take a positive step toward committing it. In this case the crime seems to be accepting assistance from a foreign government by a campaign committee in violation of the Campaign Financing Statute. The positive step was taking the meeting with the Russians. Butthead is cooked. And whoever was at the other end of the blocked number he called before and after the meeting is also cooked. And since Butthead can't take a poop without permission, it's a reasonable surmisal who was at the other end of those calls to the blocked number.

It's pretty safe to assume that everyone in that meeting already has a sealed indictment against them. Mueller is probably going to make President Individual-1 an unindicted co-conspirator, just like Nixon was because it completely avoids the Justice Department memo stuff.and it puts an indelible "Mark of Cain" on him. That, of course, avoids the idea that the 5th floor of the DC Circuit Court of Appeal's courthouse was cleared on Friday so no one could see President Individual-1's lawyers going into the courtroom trying to get his grand jury subpoena quashed.
