"Indeed, Michael McFaul is on the retaliatory sanction list, and he has been informed about that," a source in Russia's Ministry of Foreign Affairs said. "He was put on the list in response to U.S. travel ban on Russian citizens."

McFaul earlier wrote on Facebook that he had been banned from travelling to Russia.

"[I] was told that I am the Kremlin's sanctions list because of my close affiliation with Obama. I will take that as a compliment!" he wrote.
