This is pretty interesting. The Trumpsters may be right that the collusion story is fading, but they may have bigger things to worry about. It would be easier to prove obstruction, especially considering the way Trump just can't keep his tweet shut: It Is Now an Obstruction Investigation Obstruction itself is a process crime — i.e., it relates to interference in the investigation of an underlying transaction that may or may not be criminal. In the first point, above, we noted that prosecutors generally do not let a cooperator settle a case by pleading guilty to a mere process crime. But if the main case the prosecutor is trying to build is itself a process crime, such as obstruction, then it is not all that damaging that the witnesses have pled guilty only to process crimes. The theme of such a prosecution is that the investigative process must be protected, not that some terrible underlying crime (like an espionage conspiracy) has been committed. Witnesses such as Flynn and Papadopoulos would therefore not be made to look like they had gotten a pass on serious offenses; they would look like they had owned up to corrupting the process and are now helping the prosecutor against the principal corruption target. .
