Retired US Lt. Gen. Keith Kellogg, Trump's special envoy to Ukraine and Russia, is in Kiev where on Thursday he had an (apparently) brief meeting with Ukrainian President Volodymyr Zelensky.

A scheduled post-meeting news conference has been unexpectedly canceled, though no reason was immediately forthcoming, according to a Ukrainian official, presidential spokesman Serhii Nikiforov. The US side made no comment upon the presser's cancelation.

The Associated Press observes, "When the meeting began, photographers and video journalists were allowed into a room where the two men shook hands before sitting across from each other at a table at the presidential office in Kyiv."

Trump further said that Zelensky chose to sleep instead of meeting with the high-ranking American official to discuss the White House proposed mineral rights deal. "Zelensky was sleeping and unavailable to meet him," Trump told reporters aboard Air Force One.
