UPDATE 2/10/17: It was reported on 2/9/17 that Ret. Lt. General Mike Flynn did discuss with the Russian ambassador, the issue of recent US sanctions placed against it in retaliation for its meddling into the 2016 US presidential elections, and that this event occurred before 1/20/17 while President Barack Obama was still in office.
There is something called the “Logan Act” which the republican President-elect Donald Trump’s pick to be his national security advisor, Retired Lt. General Mike Flynn may have violated by his having taken the initiative to discuss policy with a foreign official prior to 1/20/17, when his boss moved into the White House.
As per Wikipedia, “the Logan Act (1 Stat. 613, 18 U.S.C. § 953, enacted January 30, 1799 ) is a US federal law that forbids unauthorized citizens from negotiating with foreign governments having a dispute with the U.S. It was intended to prevent the undermining of the government’s position.”
In a 1/12/17 Washington Post article, David Ignatius asked the question as to why the retired general was frequently calling Russian Ambassador Sergey Kislyak several times on Dec. 29, 2016 which was the same day that the U.S. imposed sanctions against Russia in retaliation for all of its actions involved in its meddling with the 2016 US presidential elections.
“Retired Lt. Gen. Michael T. Flynn, Trump’s choice for national security adviser, cultivates close Russian contacts. He has appeared on Russia Today and received a speaking fee from the cable network, which was described in last week’s unclassified intelligence briefing on Russian hacking as “the Kremlin’s principal international propaganda outlet.”
“According to a senior U.S. government official, Flynn phoned Russian Ambassador Sergey Kislyak several times on Dec. 29, the day the Obama administration announced the expulsion of 35 Russian officials as well as other measures in retaliation for the hacking. What did Flynn say, and did it undercut the U.S. sanctions? The Logan Act (though never enforced) bars U.S. citizens from correspondence intending to influence a foreign government about “disputes” with the United States. Was its spirit violated? The Trump campaign didn’t immediately respond to a request for comment.”
