Mr Burr said the panel has confirmed the findings of U.S. intelligence agencies - that Russian Federation had interfered in the election - but that one portion of the investigation has not yet closed. "And we're not in a position to come to any type of finding".
Burr said that the committee would not make the Facebook ads public.
But Warner painted a picture of widespread Kremlin-driven activity.
Warner later added that there was a "large consensus" that Russians had hacked into political files and strategically released them with the goal of influencing the election.
Burr said the Russians had been "pretty darn successful" in fomenting chaos in the US political system. He warned that the media has only gotten "glimpses" into their investigation.
Nawaz Sharif's indictment deferred; children issued non-bailable arrest warrants
The court ordered Sharif, his two sons, his daughter and a son-in-law to appear in court on October 9 to face corruption charges. Sharif accompanied by his political aide, Senator Asif Kirmani arrived at the court amid tight Rangers deployment.
"You can't walk away from this and believe Russia's not now active in trying to create chaos in our election process", Burr said.
Burr said the staff agrees with the conclusions of the intelligence reports that Russian Federation actively interfered in the election with the objective of trying to hurt Hillary Clinton and help President Trump. "The committee can not really decide the credibility of the dossier without understanding things like who paid for it, who are your sources and sub-sources". "We believe that the american people deserve to know firsthand".
Congress and Special Counsel Robert Mueller are now trying to determine whether Trump associates helped the Russians in targeting the ads.
He added that the ads "tried to create chaos [and] I would say they have been pretty darn successful". They've also interviewed Jared Kushner, Trump's son-in-law and confidant. The committee hopes to talk to 25 more witnesses later this month.
Facebook is set to testify at a Senate hearing on Russia's interference and its role next month. Burr and Warner said the government must be proactive ahead of next year's midterm elections.

A Facebook spokesperson told BI early last month that the company was "unable" to release the ads "due to both federal law and the fact that investigations are ongoing with the relevant authorities".
A number of Russian-linked Facebook ads specifically targeted MI and Wisconsin, two states crucial to Donald Trump's victory last November, according to four sources with direct knowledge of the situation.
Mark Warner criticized Twitter last week for its response to Russian meddling, calling the company's briefing to congressional investigators "deeply disappointing".
Warner also said that the Russian intelligence service activities did not end with the US presidential election on November 8 and that similar acts continued ahead of political elections in Montenegro, Belgium, France, and Germany.
"I also strongly believe that the RT ads on Twitter should be made public; a review of a representative sample reveals that they are nearly entirely created to push Russian news coverage adverse to Secretary Clinton's campaign", said Schiff in a statement. "Their response was frankly inadequate on every level".
Google officials said in a statement Friday that they are looking for evidence of Russian meddling within their system, but have not announced any findings.
