President Donald Trump announced a narrowing of General Keith Kellogg's role as special envoy, removing him from any dealings with Russia.

Some high-ranking former Russian officials have complained that Kellogg was, in their view, too sympathetic to Kyiv.

U.S. President Donald Trump appointed General Keith Kellogg as Special Envoy to Ukraine on March 15, where he will communicate directly with Ukrainian leadership rather than participate in negotiations with Russia as previously intended.
