U.S. Ambassador to Russia Michael McFaul on Sunday accused the Russian government of leaking his private conversations.

"There is no doubt that I am a primary subject of interest for them, and from time to time they have also leaked conversations I've had that I thought were private," McFaul said on NBC's "Meet The Press."

McFaul's comments came on the heels of a leaked phone call involving Secretary of State for European and Eurasian Affairs Victoria Nuland. In the call, Nuland is apparently heard saying,  "F--- the E.U." She has since apologized.

White House press secretary Jay Carney has suggested Russia was behind the leaking of the call.

McFaul characterized the U.S.-Russia relationship as one of "some cooperation, some disagreement." He plans to step down as ambassador following the Winter Olympic Games in Sochi.
