U.S. adviser Bolton set to visit Ukraine, he says on Twitter

John Bolton, U.S. President Donald Trump's national security adviser, said late on Monday he was set to travel to Kyiv, the first trip to Ukraine by a top U.S. official since the election of President Volodymyr Zelenskiy. Zelenskiy, a television sitcom star, was elected in a landslide in May and strengthened his power base at a parliamentary election last month.

"I'm looking forward to my upcoming meetings with our partners in Kyiv. We support President Zelenskyy's reform efforts and vision to create a stronger and more prosperous Ukraine," Bolton wrote on Twitter late on Monday. He did not say when exactly he planned to visit Kyiv.
