Which, yet again, is not the same as criminal conspiracy (although it was probably that as well). From The New York Times:

The Biden administration revealed on Thursday that a business associate of T____ campaign officials in 2016 provided campaign polling data to Russian intelligence services, the strongest evidence to date that Russian spies had penetrated the inner workings of the Trump campaign.

The revelation, made public in a Treasury Department document announcing new sanctions against Russia, established for the first time that private meetings and communications between the campaign officials, Paul Manafort and Rick Gates, and their business associate were a direct pipeline from the campaign to Russian spies at a time when the Kremlin was engaged in a covert effort to sabotage the 2016 presidential election.

Previous government investigations have identified the T____ aides’ associate, Konstantin V. Kilimnik, as a Russian intelligence operative, and Mr. Manafort’s decision to provide him with internal polling data was one of the mysteries that the special counsel, Robert S. Mueller III, sought to unravel during his two-year investigation into Russia’s election meddling.

“During the 2016 U.S. presidential election campaign, Kilimnik provided the Russian Intelligence Services with sensitive information on polling and campaign strategy,” the Treasury Department said in a news release. “Additionally, Kilimnik sought to promote the narrative that Ukraine, not Russia, had interfered in the 2016 U.S. presidential election.”

Rachel Maddow responded on her MSNBC program tonight:

We now know the T____ campaign secretly gave their own data to Russian intelligence in the middle of that attack, which again presumably helped what the Russians were doing. . . . 

What’s the definition of collusion again? Not just passively benefiting from somebody else’s crime, but actively helping them commit it? Is that what we call collusion? Tell me more about how the whole Russia thing is a hoax.

Maddow covered the topic for more than 20 minutes. As of this moment, the whole segment  is available on YouTube. Twelve minutes is available from MSNBC.
