An adviser to Ukrainian President Volodymyr Zelensky said Sunday night that US Secretary of State Antony Blinken and Secretary of Defense Lloyd Austin were meeting with the Ukrainian leader in Kyiv.

The adviser, Oleksiy Arestovych, said in an interview on Ukrainian TV late Sunday that the talks are going on "right now."

The trip by two of President Joe Biden's top cabinet members was kept closely under wraps. The White House has not confirmed any visit. The State Department and Pentagon declined to comment.

Zelensky earlier said he was "expecting specific things and specific weapons" from world leaders who come to the country. He said he would ask Blinken and Austin for more powerful weapons during their talks.

“We are inspired by the resilience of Orthodox Christians in Ukraine in the face of President Putin’s brutal war of aggression,” Blinken said on Twitter. “We are continuing to support them and, today, we wish them and all others celebrating Easter hope and a swift return to peace.”
