The United States Senate Intelligence Committee concluded that the Kremlin launched an aggressive effort to meddle on behalf of Donald Trump in the 2016 presidential contest as its fifth and final report was released by the Republican-led panel on Tuesday in its investigation into electoral interference.

The study (PDF) also alleged that the WikiLeaks website played a central role in Russia's attempt to manipulate the 2016 election and possibly knew Russian intelligence was supporting it.

The report purposely does not come to a final conclusion about whether there is enough evidence that President Trump's campaign coordinated or colluded with Russia to sway the election to him and away from Democrat Hillary Clinton, leaving its findings open to partisan interpretation.

Former Trump campaign chairman Paul Manafort worked with Russians, the report alleges, including oligarch Oleg Deripaska, before during and after the 2016 election that pitted Trump against Clinton.

It lays out significant contacts between Trump associates and Russians, describing for instance a close professional relationship between Trump campaign chairman Paul Mananfort and Konstantin Kilimnik, who  the committee describes without equivocation as a Russian intelligence officer.

The panel found Manafort's role and proximity to Trump created opportunities for Russian intelligence, saying his "high-level access and willingness to share information with individuals closely affiliated with the Russian intelligence services ... represented a grave counterintelligence threat".

The report notes how Manafort shared internal Trump campaign polling data with Kilimnik and says there is "some evidence" that Kilimnik may have been connected to the Kremlin's operation to hack and leak Democratic emails, though it does not describe that evidence. In addition, the report says that "two pieces of information" raise the possibility of Manafort’s potential connection to those operations, but what follows next in the document is blacked out.

According to the Senate paper, Russia was attempting to discredit inquiries into its role in electoral meddling.

"From late 2016 to at least January 2020, the Committee identified multiple Russian-government actors regularly circulating conflicting false narratives that sought to undermine investigations into Russian interference in the 2016 U.S. elections and disseminate false information about the 2016 events," the report said.

The Senate panel described its report, totaling more than 1,300 pages, as "the most comprehensive description to date of Russia's activities and the threat they posed". The bipartisan investigation lasted almost three and a half years, much longer than the other probes.

The  latest assessments were contained in the fifth and final chapter of the Senate Intelligence Committee's report on allegations that Russia sought to help Trump defeat Clinton.

Previous chapters have ratified US spy agencies' findings, made public in January 2017, that Russia had sought to help Trump in 2016 by denigrating Clinton, making it harder for her to win, and harming her presidency if she did.

A group of Republicans on the panel presented the report with "additional views" that it should state more explicitly that Trump's campaign did not coordinate with Russia. But Democrats on the panel put forward their own views, arguing that such collaboration is clearly shown in the study.

The most comprehensive public account of the 2016 election debacle is likely to be the last chapter of the committee report released as Trump prepares to face off against Joe Biden in the 2020 presidential election.
