A Hillary Clinton campaign cut-out hires the (former?) British intelligence agent Steele to pay money to (former?) Russian intelligence agents and high-level Kremlin employees for dirt about Donald Trump. They deliver some dirty fairy tales. The resulting dossier is peddled far and wide throughout Washington DC with the intent of damaging Trump.
Some lobbyist for Russian business interests contacts the Trump campaign with a promise to deliver some dirt on Hillary Clinton. She meets campaign officials but no dirt on Clinton is offered. Instead the lobbyist uses the time to lobby for the business' cause. There is no follow up.
Which of the two cases stinks of "collusion with the Russians"?
