Is Obama lying about his letter to Medvedev?

I’m guessing he IS doing something along those lines called “ walking it back” and trying to delink his actual letter linking realigning a U.S. missile shield if Russia would stop helping Iran with nuclear and missile technology.

Russian President Dmitry Medvedev said no, and leaked the letter to the New York Times, which reported on it.

And now, Obama’s trying to pretend he never sent such a letter.

More proof Just.Another.Politician.™ is lying? Members of his own administration told U.S. media about the letter.

Obviously, he won’t be believed in Russia; no telling who will, or will not, swallow his claim over here.
