Senate Intelligence Committee Chairman Richard Burr (R-N.C.) (L) and committee Vice Chair Mark Warner (D-Va.) hold a news conference on the status of the committee's inquiry into Russian interference in the 2016 presidential election at the Capitol on October 4, 2017 in Washington.
The committee chairman, Republican senator Richard Burr, said it remained an "open question" whether there was collusion by the Trump campaign with Moscow.
"We will share with you when we have exhausted every thread of intelligence, every potential witness that can contribute anything to this", he said.
"It seems that the overall theme of the Russian involvement in the US election was to create chaos at every level", he said.
The assessment concluded that Russian President Vladimir Putin ordered a campaign to undermine the US election and favor then-candidate Donald Trump over Hillary Clinton.
The Senate intelligence committee has said it has confidence in an United States agency finding earlier this year that Russian Federation intervened in the USA presidential election in an effort to skew the vote in Donald Trump's favour.
Burr later said that they will not be releasing Facebook ads that were paid for by Russian entities.
"The committee continues to look into all evidence to see if there was any hint of collusion", Burr told reporters during a press conference regarding the status of the Russian Federation investigation Wednesday afternoon.
But, these people said, the ads also targeted nonbattleground states like California, Maryland and NY - solid Democratic states that are normally not decisive in presidential elections - and the Republican strongholds like Texas, Alabama and MS the people familiar with the ads said.
The Russian efforts, Warner said, "did not end on Election Day in 2016".
One witness the politicians say they have been unable to question is Christopher Steele, a former British spy believed to have compiled a dossier of allegations about Mr Trump's connections to Russian Federation.
Sources with direct knowledge of the situation say Russian-linked Facebook ads specifically targeted MI and Wisconsin.
Burr and Warner may divulge more information about social media's role in the election.
Facebook officials have said that 10 million people saw Russia-linked advertising that sought to sway the US presidential election on the social media platform, and 44 percent of those were seen before the election.
Burr said Wednesday that the committee has not seen any evidence that the activities favored either Republicans or Democrats.
The committee appeared to leave any further probing of the Comey memos to Special Counsel Robert Mueller, who is leading an independent investigation on behalf of the Justice Department.
"I think we will address a lot of things on Wednesday at our press conference", Burr said.
