"We have made our concerns crystal clear to both sides that if the deal were to move forward, it would raise serious concerns," State Department spokeswoman Marie Harf said during a news briefing.
Harf's comments were bolstered by Treasury Undersecretary David Cohen, who is responsible for U.S. sanctions. Speaking at a Senate hearing, Cohen said he had seen many reports about an imminent Iran-Russian deal, none of which had come to fruition so far. If true, however, he said the United States would be ready to impose penalties.
