Secretary of State Antony Blinken announced on Monday that the U.S. would shutter its embassy in Kyiv amid threats of a Russian invasion into Ukraine that officials warn could be launched at any time.

The document destruction was discussed in a call on Feb. 12 between Deputy Secretary of State for Management and Resources Brian McKeon and Chairman of the House Foreign Affairs Committee Gregory Meeks (D-N.Y.), notes of which were provided to congressional staff and obtained by The Hill.  

The documents being destroyed include green card and non-processed passport documents.

Among the updates McKeon provided to Meeks was that while the State Department does not have an exact picture of the numbers of Americans in Ukraine, about 2,100 responded to an online survey, with half stating their intention to stay in the country.
