"Is the source anonymous? Then they understand that their conscience is not clear. As for the essence, then — if so — this is daylight robbery," Lavrov told reporters in Belarus.
Lavrov added that russophobia in the United States does not give assurances that Moscow and Washington would be able to agree on key international issues.
"Such a zealous sense of urgency in seeking out some hidden channels of Russian influence over what is happening in the United States is clearly not subsiding, to my great regret, and does not add confidence that we would be able to establish normal cooperation in international relations," Lavrov said.
In December 2016, Washington imposed a number of restrictive measures on Russia over Moscow’s alleged meddling in the US presidential election, including sanctions against several Russian individuals and entities, as well as the expulsion of 35 Russian diplomats and the closure of two Russian diplomatic compounds in the United States.
