"During the hearing, the judge also appeared to allude to another possible interaction at the Havana Room gathering: a handoff by Manafort of internal polling data from Trump's presidential campaign to his Russian associate.
The new details provide a rare hint at what Mueller is examining in the final stretch of his nearly 21-month-old investigation -- and underscore his deep interest in the Grand Havana Room gathering, which ended with the three men leaving through separate doors, as Judge Amy Berman Jackson noted.
The Grand Havana Room meeting took place during a critical moment in the 2016 race.
Less than two weeks earlier, the issue of Russia's role in the campaign exploded into view when WikiLeaks published thousands of emails stolen from the Democratic National Committee. Democratic candidate Hillary Clinton's supporters immediately fingered Russia in the hack, a view later embraced by U.S. intelligence agencies.
Trump also made a series of public statements in July that appeared to echo Kremlin talking points on foreign policy. In an interview with the New York Times, he questioned the U.S. commitment to defending NATO partners from Russian aggression. Then he promised to look into recognizing Russia's invasion of Crimea.
There are also indications in the transcript of last week's hearing that prosecutors have explored whether it was at the Manhattan cigar bar that Manafort shared polling data related to the 2016 White House race with Kilimnik -- another topic about which Manafort lied, they allege.
The sharing of that data was first disclosed, apparently inadvertently, in a court filing by Manafort's attorneys last month. At the time, it was unclear when Manafort passed along the information to his Russian employee -- as well as the substance of the material."
