A US delegation led by Army Secretary Dan Driscoll is in Kyiv on a "fact-finding mission", the US embassy in Kyiv said.
Driscoll, along with Army Chief of Staff General Randy George, will meet Ukrainian President Volodymyr Zelenskyy on Thursday, a person familiar with the matter told Reuters news agency.
Driscoll's trip to Ukraine to discuss the country's drone warfare innovations and tactics was in the making for some time, a US official who requested anonymity told Reuters.
The official also said that last week President Trump decided to identify him as a kind of "special representative" to kickstart peace negotiations and execute a fact-finding mission.
