MOSCOW (Sputnik) — McFaul wrote in his Facebook blog earlier on Friday that he had been put on Russia's sanctions list and could not travel to Russia.
"McFaul is indeed on the mirror sanctions list, and he knew about it," the source told RIA Novosti.
"He has been included in the list…for active participation in the destruction of bilateral relations and as a staunch lobbyist of a pressure campaign against Russia," the source stressed.
McFaul served as US ambassador to Russia in 2012-2014.
Russia already introduced entry restrictions for a number of nationals from the United States, the European Union and other countries in the spring of 2014. The move came in response to sanctions against Russian officials, introduced on the pretext of Crimea’s reunification with Russia and the crisis in eastern Ukraine.
