Jill Stein has acknowledged attending a 2015 event in Moscow celebrating the anniversary of a state-sponsored Russian news organization.
The Senate Intelligence Committee has requested Jill Stein turn over specific documents, according to a BuzzFeed News report.
Stein said in a statement overnight Tuesday that she was cooperating with the probe and is providing documents to the committee.
Trainor said he was informed of the committee's request because he was "a primary point of contact" for Stein during the campaign trail. While the investigation has largely focused on both the Russian interference and whether it was in any way connected to President Donald Trump's campaign, investigators are following multiple leads.
Stein requested to speak to Putin, Russian Foreign Minister Sergey Lavrov. or someone in the Russian government to discuss her policies, but the request was not granted, she told the Intercept.More news: Fans Mourn Death of K-Pop Star Jonghyun

Michael Flynn, who later became Trump's national security adviser, also attended the 2015 dinner in Moscow. Flynn recently pled guilty to lying to the Federal Bureau of Investigation about a meeting with Russian ambassador Sergey Kislyak and is now cooperating with Special Counsel Robert Mueller.
Politico reported in September that Stein also benefited from Facebook political advertisements purchased by Russian accounts. Russian Federation has consistently denied any interference in the election.
"[We] made the trip with the goal of reaching an global audience and Russian officials with a message of Middle East peace, diplomacy, and cooperation against the urgent threat of climate change, consistent with long-standing Green principles and policies", Stein wrote on Facebook. Richard Burr (R-NC), who chairs the Intel committee that's probing possible Trump-Russia collusion, told reporters on Monday that Stein's campaign - which received about 1 percent of the vote in 2016 - is one of "two other campaigns we're starting on" for possible collusion with the Kremlin.
The House Intelligence Committee is interviewing a number of high-profile witnesses this week, according to the Boston Globe.
Still, Stein clearly resents the Senate's attention vis a vis electoral interference and foreign meddling: "This smacks of the risky underbelly of these investigations".
