EU's Tusk credits U.S. for Western unity against Russia
Donald Tusk says EU's unity against Russia over Ukraine was maintained thanks to the support of the U.S. - specifically, of Barack Obama.
"We may criticize some of his decisions, but I had his support constantly. We managed to maintain that solidarity front," the president of EU's European Council and former Polish prime minister has told private Polish television TVN24.
