Six of the previously undisclosed contacts described to Reuters were phone calls between Sergei Kislyak, Russia's ambassador to the United States, and Trump advisers, including Flynn, Trump’s first national security adviser, three current and former officials said, according to Reuters.
Conversations between Flynn and Kislyak accelerated after the Nov. 8 vote as the two discussed establishing a back channel for communication between Trump and Russian President Vladimir Putin that could bypass the U.S. national security bureaucracy, which both sides considered hostile to improved relations, four current U.S. officials said.

But the disclosure could increase the pressure on Trump and his aides to provide the FBI and Congress with a full account of interactions with Russian officials and others with links to the Kremlin during and immediately after the 2016 election.
The 18 calls and electronic messages took place as hackers engaged in a Kremlin campaign to discredit the vote and influence the outcome of the election in favor of Trump over his Democratic challenger, former secretary of state Hillary Clinton.
In addition to the six phone calls involving Kislyak, the communications described to Reuters involved another 12 calls, emails or text messages between Russian officials or people considered to be close to Putin and Trump campaign advisers.
One of those contacts was by Viktor Medvedchuk, a Ukrainian oligarch and politician, according to one person with detailed knowledge of the exchange and two others familiar with the issue.

Medvedchuk denied to Reuters having any contact with anyone in the Trump campaign.
Veterans of previous election campaigns said some contact with foreign officials during a campaign was not unusual, but the number of interactions between Trump aides and Russian officials and others with links to Putin was exceptional.
