Let me ask, if police get a warrant to search someone's home for potential kidnapping victims and finds instead a drug operation, do they not have grounds to arrest for the discovered offense, even if it was not the original suspicion? crimes are crimes, however they are discovered. It is up to congress to decide on a charge of OBSTRUCTION, COLLUSION has already been nixed as there is not definitive PROOF.
OJ was found not guilty of murder, even though a large population believed he was. But later he WAS found guilty of robbery. So absence of proof of one crime is not the same as absence of proof of ANY CRIME.
But in Trumps case, again, a charge of OBSTRUCTION (of the investigational procedure) could be supported by the TEN instances in which the investigation found.

WASHINGTON (AP) — The president’s communications director didn’t sugarcoat it: The emails, Hope Hicks told Donald Trump, were “really bad.”
"They concerned an as-yet unpublicized meeting in Trump Tower a year earlier involving Donald Trump Jr., his brother-in-law, Jared Kushner, and former campaign chairman Paul Manafort.
The emails showed how the president’s oldest son had accepted a meeting with a Russian lawyer with the promise of receiving dirt on his father’s opponent, Hillary Clinton. Not only that, he’d been told the dirt was part of the Russian government’s ongoing support for his father.
“I love it,” Trump Jr. had replied".
