KIEV, June 19 – President Petro Poroshenko has left on a working visit to the U.S., and - despite the lack of clarity on the part of U.S. officials - his press secretary Svyatoslav Tsegolko is still insisting that a meeting with President Donald Trump is in the cards.

"The president of Ukraine has left for a working visit to the United States," Tsegolko wrote on his Facebook on Monday.

On June 14, a source in diplomatic circles has told Interfax-Ukraine Poroshenko will pay a visit to Washington next week, where he will hold a meeting with U.S. President Donald Trump. "Indeed, an agreement was achieved on the meeting [with Trump], the visit will be held on June 19-20," the source said.
