"The issue of collusion is still open, that we continue to investigate both intelligence and witnesses, and that we're not in a position where we will come to any type of temporary finding on that until we've completed the process", Burr said.
Burr said the committee had interviewed every official who had a hand in writing the assessment, adding that staff and lawmakers spent "nine times as long" reviewing the report as the officials spent writing it. Burr and Warner are keeping their committee clear of that question, and another panel, the Judiciary Committee, has locked horns with the Justice Department about getting witnesses for its own inquiry.
Senate Intelligence Committee Chairman Richard Burr said Wednesday that the panel "has more work to do" to determine whether there was collusion between Russian officials and Donald Trump's team during last year's presidential election.
The panel has expanded its probe and refused to rule out possible conclusion between the Trump campaign and Russian Federation, and the chairmen warned the Kremlin had not stopped its efforts to influence elections.More news: Afghanistan pull-out would be 'to our ultimate peril': James Mattis
The committee, Burr said, has determined that the Russian involvement in buying ads on social media was "indiscriminate" and did not benefit "one side of the ideological spectrum or the other".
But Burr added, "We have been incredibly enlightened in our ability to rebuild backwards the Steele dossier up to a certain date".
"We know the Russian meddling did not end after the elections". An FBI investigation began in July 2016.
"The committee can not really understand the credibility of the dossier without understanding who paid for it and who were your sources and sub-sources", Burr said. "Who were your sources?"More news: GM To Release 20 Electric Cars By 2023
Senator Richard Burr (R-NC) and Mark Warner (D-VA) speak at the Senate Intel Committee press conference on October 4, 2017. Mark Warner, D-Virginia, warned that the investigation has indicated that Russian agents are continuing efforts to influence results at the ballot box.
Republican Chairman Richard Burr and Democratic Vice Chairman Mark Warner also warned about the risk to future USA elections posed by Russian Federation, including what is expected to be a closely contested election next month for governor of Warner's home state, Virginia.
But Schiff added that Russia's attempts to interfere in USA elections "is not over" and said all Facebook ads that were Russian-bought should be publicly available to every American. He did not elaborate, except to say that the committee had not come to any conclusions and that the investigation is ongoing. Facebook surrendered the content of thousands of ads to Congress this week and it has acknowledged that some 10 million Americans may have seen them from 2015 to earlier this year.
