I’ll quote the first three paragraphs of the article and provide the link to the whole thing.  Note that it actually originated from the Wall Street Journal but is behind a pay wall.  The quotes are from Salon:
 

The U.S. intelligence community has long since concluded Russia meddled in the 2016 election, and it was reported shortly after the 2016 presidential election that a GOP superPAC linked to Paul Ryan used illegally hacked material to attack Democratic House candidates. But a bombshell report published on Thursday confirms that Republican political operatives were working with the Russian government to hurt Hillary Clinton and Democrats during the election — the first direct evidence of so-called collusion.

The Wall Street Journal reported that hacked information was posted on a blog run by Aaron Nevins, the political operative, and then passed along to top Trump adviser Roger Stone during the campaign. The Republican operative in Florida received a trove of Democratic documents from the allegedly Kremlin-linked hacker, Guccifer 2.0. For months, both Congress and the FBI have been scrutinizing evidence that associates of Trump may have colluded with Russia during the campaign.

Nevins confirmed to the Journal that he told hacker Guccifer 2.0 to “feel free to send any Florida based information” after learning that the hacker had tapped into Democratic Congressional Campaign Committee (DCCC) computers last summer. From the DCCC, Guccifer 2.0 released internal assessments of Democratic congressional candidates, known as “self-opposition research,” to GOP operatives using social media. Nevins told the Journal that, after receiving the stolen documents from the hacker, he “realized it was a lot more than even Guccifer knew that he had.” The stolen DCCC documents also contained sensitive information on voters in key Florida districts, breaking down how many people were considered dependable Democratic voters, undecided Democrats, Republican voters and the like. Nevins made a war analogy, describing the data he received to Guccifer 2.0 as akin to a “map to where all the troops are deployed.”
