President Trump told the Washington Post today he's considering cancelling a meeting later this week with Vladimir Putin after Russia seized three Ukrainian ships Sunday off the coast of Crimea. Ukrainian President Petro Poroshenko, meanwhile, told NBC News that he's asking Trump to make a demand of Putin in the meeting: "Get out of Ukraine."
The backdrop: Ukraine's parliament voted yesterday to impose martial law for 30 days in areas under threat from Russia, which is still holding 24 Ukrainian sailors after Sunday's incident. Poroshenko told CNN Russia was concentrating troops near the border, and the order was needed to "move troops more easily" and "defend our territorial integrity." The conflict is now likely to play a central role in the Trump-Putin meeting, assuming it goes ahead.
