Lavrov called the U.S. allegations about election meddling "groundless" and "without proof," CNN reported. "We cannot not respond to this," he said. "This goes against the law of diplomatic relations." But Russia denied a CNN report that Russian authorities had ordered the closure of the Anglo-American School in Moscow to US and foreign nationals. Posting on her official Facebook account, Russian Foreign Ministry spokeswoman Maria Zakharova said: "American officials have 'anonymously briefed' their mass media about the fact that as a retaliatory measure Russia has closed the American School in Moscow. This is a lie. Clearly, the White House has completely lost its senses and begun to invent sanctions against its own children.
