“We were focusing on him, we knew he was influential. We had information that he wanted to be president in future.”

The scale of Soviet Moscow’s spying operation on Trump is unknown. No documents are public. It is unclear when the KGB began a file on the future president. In Prague about 60,000 StB documents were declassified in the mid-1990s, after the collapse of communism. The StB destroyed most records.

However, secret memos written by the KGB chief, Vladimir Kryuchkov, in the mid-1980s reveal that he berated his officers for their failure to cultivate top-level Americans. Kryuchkov circulated a confidential personality questionnaire to KGB heads of station abroad, setting out the qualities wanted from a potential asset.
