WASHINGTON — Secretary of State Mike Pompeo plans to meet with President Volodymyr Zelensky of Ukraine in Kyiv on Friday, the State Department said Monday.

Mr. Pompeo will be the highest-ranking member of the United States government to meet with the Ukrainian president since Vice President Mike Pence met with him in Warsaw on Sept. 1 and the first cabinet official to meet with him since the formal start of the impeachment inquiry, which centers on President Trump’s interactions with Mr. Zelensky and his government.

Since that inquiry began in late September, Mr. Pompeo has tried to maintain his distance from the Ukraine issue. He has refused to release State Department documents demanded by impeachment investigators in the House and has declined to speak in any detail about his own role in the affair.

But on several occasions, he has reiterated some of Mr. Trump’s positions on potential investigations related to Ukraine. And he has refrained from publicly supporting ambassadors and senior diplomats who have testified before Congress and come under attack by Mr. Trump. That has contributed to a sharp drop in morale at the State Department.
