President Donald Trump erupted in anger when he learned the U.S. was expelling 60 Russian diplomats in March, while France and Germany were only expelling four each, the Washington Post reported late Sunday. Trump reportedly only wanted to match the number of allies' expulsions, and not to be seen as taking the lead. Trump believed his aides misled him, the Post said. "There were curse words," one official told the Post, "a lot of curse words." The expulsions were the most ever by the U.S. against Russia, and came in response to a suspected Russian nerve-agent attack on a former spy and his daughter in England. Separately, the Trump administration appears ready to impose more sanctions on Russia. Nikki Haley, the U.S. ambassador to the United Nations, said Sunday that a new round of sanctions will target Russian companies that aid Syria's chemical weapons capabilities.
