Senate Intelligence Committee Ranking Member Mark Warner defended his committee's ongoing investigation into allegations President Trump colluded with Russia during the 2016 election.

Martha MacCallum asked Warner (D-Va.) about his GOP counterpart, Chairman Richard Burr of North Carolina, claiming that there is "no factual evidence of collusion."

"If we just look at what is in the public domain ... people can draw their own conclusions," Warner responded.

Warner said that, based on Michael Cohen's testimony before Congress last week, Trump knew about business-related negotiations -- during the early part of his campaign -- between his real estate firm and Russia.

He said that such negotiations regarding a potential Trump Tower in Moscow were not illegal, but a "relevant fact."

"I've never seen this many contacts between a candidate, [his] business organization and a foreign power," Warner said.

MacCallum noted that 2016 Democratic contender Hillary Clinton was also "very anxious to talk to Russia" at times.

Warner concluded that he is formally "reserving judgment" on what the result of his investigation will be, but said that Russia did indeed "intervene" in the election in a way that benefited Trump and not Clinton.
