Putin's spokesman told the BBC that "there is nothing to respond to questions or issues like this because they obviously fictional."Putin's spokesman, Dmitry Pskov, commented at a press conference that "this is a formal accusation" and demanded evidence. However, Pskov added that "the relationship between us [the US and Russia] at the moment is not at its best, and in this situation a lie could deteriorate it even further." Russian Foreign Minister Sergei Lavrov also commented and said that his country wants to restart its relations with the United States.
