Is this perhaps the one “scapegoat” they’ll use to bring a close to the investigation? Surely Mueller knows the truth by now: Trump did not ‘collude’ with the Russians.
Really, there is no law about colluding except in price fixing, which has nothing to do with this subject. However, there are laws about lying to the FBI and obstruction of justice. Why did he feel the need to lie? He lied to VP Pence and was fired for it. Was it mere vanity or something more serious? No one really knows yet.
