Trump says Russia told U.S. "most of their people" have left Venezuela

President Trump said the Russian government told the U.S. that "most of their people" stationed in Venezuela have left the crisis-stricken South American country.

"Russia has informed us that they have removed most of their people from Venezuela," the president wrote on Twitter Monday afternoon during his state visit to the U.K.

The State Department did not respond to a request by CBS News to clarify when and how the Russian government informed the U.S. of a personnel withdrawal in Venezuela. CBS News also asked the department to identify the information on which the president based his assertion on and to clarify what exactly Mr. Trump was referring to when he wrote "people."
