San Francisco:  The top Democrat working on the Senate Intelligence Committee's Russia probe doesn't see his party ramping up investigations into Moscow's efforts to meddle in the 2016 election should they win control of Congress in November elections.

Americans "will be tired of it if this is not wound down in this calendar year," Senator Mark Warner of Virginia at the Recode Code Conference in California.

Warner said members on the panel are being pushed in different directions: Republicans to end the probe and Democrats to conclude there was collusion between Russia and President Donald Trump's campaign.

"There's enormous pressure on some of the Republicans to say, 'Hey, you know, it's time to get this thing over, let's shut it down,'" Warner said. "On the other hand, on the Democratic side there's a lot of pressure to say 'Hey, you know, of course there is collusion, call this guy out as guilty tomorrow, don't wait for the process to finish."'

While the House Intelligence Committee has fractured along partisan lines, ending its investigation by issuing conflicting reports, Warner and Senator Richard Burr, the Senate committee's Republican chairman, have maintained a bipartisan effort.
