Senate Intelligence Committee Chairman Sen. Richard Burr, accompanied by Senator Mark Warner, vice chairman of the committee, speaks at a news conference to discuss their probe of Russian interference in the 2016 election on Capitol Hill in Washington

WASHINGTON (Reuters) - The Republican chairman of the U.S. Senate Intelligence Committee on Wednesday promised a thorough investigation into any direct links between Russia and Donald Trump during his successful 2016 run for the White House.
Committee chairman Richard Burr and Mark Warner, its top Democrat, pledged at a joint news conference that they would work together, in contrast with the partisan discord roiling a similar probe by the House of Representatives Intelligence Committee.
Burr was asked if the Senate panel wants to determine if there is anything suggesting a direct link to Trump and responded, "We know that our challenge is to answer that question for the American people."
Trump's young presidency has been clouded by allegations from U.S. intelligence agencies that Russia sought to help him win while connections between his campaign personnel and Russia also are under scrutiny. Trump dismisses such assertions and Russia denies the allegations.
The Senate committee intends to begin interviewing as many as 20 people, including Jared Kushner, Trump's son-in-law and one of his closest advisers, beginning as early as Monday.
Burr served as a security adviser to Trump's campaign but said he has not coordinated with him on the scope of the committee's investigation. He insisted he could remain objective.
Burr declined to go along with the White House's denial of collusion between the campaign and Russian hackers, who U.S. intelligence officials believe favoured Trump in last year's campaign at the expense of Democratic challenger Hillary Clinton.
"We would be crazy to try to draw conclusions from where we are in the investigation," Burr said. "Let us go a little deeper into this before you ask us to write the conclusions. That's clearly something we intend to do down the road."
Burr and Warner would not comment on the investigation in the House, where the chairman of the intelligence committee, Trump ally Devin Nunes, has been under fire over his handling of the matter.
Many Democrats, including Adam Schiff, the top Democrat on the House intelligence panel, called for Nunes to recuse himself from the investigation after he met last week with an unidentified source at the White House complex, accusing him of colluding with the White House.
Before telling his committee colleagues, Nunes met with House Speaker Paul Ryan, and then Trump, and told reporters the source provided him with evidence that information on Trump's transition team had been collected during legal surveillance of other targets.
Both Republican and Democratic lawmakers have said the discord surrounding the House committee has made the Senate investigation more important than ever. "Clearly in the Senate, it appears that both Democrats and Republicans are acting like adults and taking this matter seriously," Democratic Representative Jim McGovern told Reuters.
'PAID INTERNET TROLLS'
Warner and Burr both stressed the importance of exposing the activity of Russian hackers, which Warner said included reports of "upwards of 1,000 paid Internet trolls" who spread false negative stories about Clinton.
Warner and Burr did disagree slightly, with Warner alluding to some difficulties getting particular documents from intelligence agencies, and Burr defending them.
The two senators also indicated they had communicated with Michael Flynn, Trump's former national security adviser, who was fired last month after misrepresenting meetings with the Russian ambassador.
"It would be safe to say we have had conversations with a lot of people and it would be safe to say General Flynn is a part of that list," Burr said.
Neither Burr nor Warner gave a timeline for finishing the investigation.
"This is one of the biggest investigations the Hill has seen in my time here," said Burr, who has been in Congress since 1995.
The senators said they also wanted to call attention to what they described as Russia's attempts to influence upcoming elections in France and Germany.
