From a story on politico.com by Nahal Toosi headlined “Lonely Anatoly: The Russian ambassador is Washington’s least popular man”:

No one wants to talk to Anatoly Antonov.

Russia’s ambassador to the United States can’t get meetings with senior officials at the White House or the State Department. He can’t convince U.S. lawmakers to see him, much less take a photo. It’s the rare American think tanker who’s willing to admit to having any contact with the envoy.

Not even Russian leader Vladimir Putin chats with him.
