So basically while there isn't evidence Trump actively colluded with a hostile foreign power to influence a US election, he did knowingly look the other way (and even encourage them) while he pursued personal business deals with them.
How is Trump not a corrupt traitor again? Sure his cult base would excuse him of anything but it's another credibility blow for a President already the least popular since WWII (at a time when the booming economy would dictate he should be popular).
