White House press secretary Sarah Sanders urged members of the Senate Intelligence Committee on Thursday to "focus on other things," a day after the panel said its probe into possible collusion between Trump associates and Russian officials remains open.

"The Senate Intel Committee told us yesterday that after nearly nine months of investigating – that's included more than 100 interviews over 250 hours; 4,000 pages of transcripts; 100,000 pages of documents; interviewing officials in the intelligence community, who wrote the report on Russian election meddling; interviewing relevant Obama administration officials, and talking to every Trump campaign official they've requested – it's literally found zero evidence of collusion between the Trump campaign and Russia," Sanders told reporters.

"I think the American people would like them to focus on some other things," she added.

Chairman Richard Burr, R-N.C., and ranking member Mark Warner, D-Va., announced at a press conference Wednesday the committee is still examining "all evidence to see if there was any hint of collusion" between the Trump campaign and Kremlin during the 2016 election.

Burr said the panel hopes to issue a final report by the end of the year, despite the probe's recent decision to look into the dissemination of "fake news" by popular social media networks during the election.

"You cannot walk away from this and believe that Russia is not currently active in trying to create chaos in our electoral process," Warner said.

Committee members also admitted Wednesday they have struggled to verify the contents of a dossier on Trump that was supposedly compiled by former British intelligence officer Christopher Steele during the election.

"We have on several occasions made attempts to contact Mr. Steele, to meet with Mr. Steele," Burr said, adding that "the committee cannot really decide the credibility of the dossier without understanding things like who paid for it, who are your sources and sub-sources."

Trump suggested in a tweet earlier Thursday the Intel committee launch an investigation "into the Fake News Networks in our country to see why so much of our news is just made up."
