Why is collusion not against the law?

12. Collusion is the wrong word to describe Russiagate--it's conspiracy, not collusion

Collusion, as I understand, describes two or more entities getting together for the purpose of price fixing, wage fixing, and other antitrust violations.
Example: No wonder prescription drugs are so exorbitant! The pharma companies have colluded to make them that way!

What the Russiagate investigation entails is the coordination of the tRump campaign--or even the administration--with Russian government interests, which is really a alleged conspiracy. They coordinated to undermine American democracy and suppant it with a vicious authoritarian regime.
