KIEV (Reuters) - John Bolton, U.S. President Donald Trump’s national security adviser, traveled to Kiev on Tuesday, the U.S. Embassy said, the first visit 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.

“Ambassador Bolton is here to underscore U.S. support for Ukraine’s sovereignty, territorial integrity and Euro-Atlantic path. He looks forward to productive meetings with Ukrainian officials,” the U.S. Embassy in Kiev wrote on Twitter.
