Sen. Mark Warner said Sunday that "in a couple of months" there will be "more clarity" in the Senate's probe into Russian involvement in the 2016 election.

In an interview with CNN’s "Fareed Zakaria GPS," the Virginia Democrat said the Senate Select Committee on Intelligence is at the "stage of starting to talk to some of the individuals who are affiliated with the Trump campaign that, at least in the press, have been mentioned that they might have had contacts with the Russians." Warner is the Senate panel's vice chairman.


He noted, though, that he had thought the investigation would be "further along" by July 4th.

When asked by host Fareed Zakaria whether there was collusion between President Donald Trump's campaign and the government of Vladimir Putin, Warner said he would not expect to have those answers until after the interviews have been conducted.

"I would not expect us to have those answers, because we've not talked to any of those Trump affiliates and Trump associates," he said. "Ask me that same question in a couple of months, and I think we'll have much more clarity."

Last week, North Carolina Sen. Richard Burr, the Republican leader of the investigation, announced that the committee is aiming to finish the probe by the end of the year.

The Senate panel is one of at least five committees digging into Russia’s role in influencing the election and whether there were ties between Moscow and Trump's campaign. Warner did say there was no doubt the Russians meddled in the 2016 elections.

Warner also said he believes there is going to be more Russian interference in elections, such as the German elections in September.

"We're going to see Russian intervention in the German elections, and I would point out, if you add up the money that the Russians have spent in America, France, the Netherlands, and Germany and double it, that's still less than 5 percent of the cost of a new aircraft carrier," he said.
