Reuters reported May 18th,

Michael Flynn and other advisers to Donald Trump’s campaign were in contact with Russian officials and others with Kremlin ties in at least 18 calls and emails during the last seven months of the 2016 presidential race, current and former U.S. officials familiar with the exchanges told Reuters.

The previously undisclosed interactions form part of the record now being reviewed by FBI and congressional investigators probing Russian interference in the U.S. presidential election and contacts between Trump’s campaign and Russia.

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.
