First Lady Jill Biden visited Ukraine Sunday, a surprise rare move for a First Lady to visit a war zone.

She met with Ukrainian First Lady Olena Zelenska. They also visited a nearby school housing migrants.

“We understand what it takes for the U.S. first lady to come here during a war when military actions are taking place every day, where the air sirens are happening every day – even today,” Zelenska said.

Biden also visited Romania to thank U.S. troops stationed there.
