"My impression of that when it comes to conflict in Ukraine we were more or less on the same line with President Trump and Secretary Tillerson. Of course, maybe I'm less optimistic when it comes to President Putin's plans and intentions, maybe less sentimental," Tusk said at a joint press briefing with European Commission President Jean-Claude Juncker ahead of the G7 summit in Taormina, Italy, on May 26, 2017.

"I think the president is looking at it. Right now, we don't have a position," Cohn said, adding that Trump had "many options" he is considering.
