Again: For it to be conspiracy, there must be violation of law. A "conspiracy theory" needs a law violated, at least in theory. Keeping or sharing secrets does not violate law -- unless the secrets are about violations of law.
Is this really difficult? Nixon had a conspiracy both to violate laws, and to cover up violating laws, making at least three violations. Trump's people probably conspired to violate laws against foreign influence on elections. Clinton didn't conspire to perjure, because it was just him.
Let's just call it a conspiracy theory then.
