Senate Foreign Relations panel to probe Russian hacking
Corker, who chairs the committee, told CNN that senators would hold open hearings as well as classified, closed-door briefings.
"We are going to systematically walk through the entire Russia issue and fully understand what has transpired," Corker said. 
Corker's decision makes the Foreign Relations panel the third Senate committee to probe allegations that Russia tried to influence the U.S. election. The Intelligence and Armed Services committees are also expected to conduct their own investigations.
Corker added Tuesday that while it's clear Russia tried to interfere in U.S. politics, it's unclear if their aim was to help elect Donald TrumpDonald John TrumpAlaska Republican Party cancels 2020 primary Ukrainian official denies Trump pressured president Trump goes after New York Times, Washington Post: 'They have gone totally CRAZY!!!!'

A spokeswoman told The Hill that the committee will begin with hearings in early January.
"The committee plans to systematically look at this issue in the broader context of our overall Russia policy and will begin with both a classified briefing and an open hearing on Russia," the aide added.

The Washington Post reported Friday that the CIA concluded Russia intervened in the election to try to help the real estate mogul.

Nine Democratic senators also said Tuesday they want a formal intelligence report on Russian tampering in the U.S. election before Trump takes office next month.

Trump dismissed the CIA's assessment in an interview Sunday, calling it "ridiculous." Trump said Monday that if the election results were reversed and he was the one making such an accusation it would be considered a "conspiracy theory."
