The charges come as U.S.-Russian relations dipped to a recent low after the Russian government expelled the U.S. Agency for International Development, accusing it of meddling in Russia's internal affairs. Russia has also voiced its displeasure with a set of human rights sanctions being pushed by Congress that would slap visa bans and asset freezes on several Russian officials allegedly tied to the death of whistle-blowing lawyer Sergey Magnitsky, who died in police custody in 2009.
Earlier this week, Russian Foreign Minister Sergey Lavrov suggested that the "re-set" in relations between Moscow and Washington, which the Obama administration proposed shortly after taking office in 2009, could not last forever.
"If we talk about the 'reset,' it is clear that, using computer terminology, it cannot last forever. Otherwise it would not be a 'reset' but a program failure," Lavrov told Kommersant newspaper in an interview.
