>Volume I of the report concludes that the investigation did not find sufficient evidence that the campaign "coordinated or conspired with the Russian government in its election-interference activities"

To quote The Intercept:
In fact, the Senate report dismisses many of the most outrageous accusations involving Trump and Russia even as it provides overwhelming and damning evidence of Russia’s efforts to intervene in the 2016 presidential election to help Trump win and the Trump campaign’s eagerness to embrace the Russian intervention.
But the Senate report goes much further than election interference and provides the first detailed examination of the broader and complex network of relationships between Trump, his ever-shifting circle of personal and business associates, and a series of Russian oligarchs and other Russian and Ukrainian figures with ties to Russian President Vladimir Putin.
