Sources says Donald Trump campaign had at least 18 undisclosed contacts with Russians

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, current and former U.S. officials familiar with the exchanges told Reuters.

The sources said the 18 calls and emails, took place in the last seven months of the 2016 presidential race.

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.

The sources said six of the previously undisclosed contacts described to Reuters were phone calls between Kislyak and Trump advisers, including Flynn, Trump’s first national security adviser, three current and former.

Conversations between Flynn and Kislyak accelerated after the Nov. 8 vote.

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.
