When did the KGB open a file on Donald Trump? We don’t know, but Eastern Bloc security service records suggest this may have been as early as 1977. That was the year when Trump married Ivana Zelnickova, a twenty-eight-year-old model from Czechoslovakia. Zelnickova was a citizen of a communist country. She was therefore of interest both to the Czech intelligence service, the StB, and to the FBI and CIA.
