These documents belong to the Communist secret service and the Ministry of the Interior of the Czechoslovak Socialist Republic (CSSR), now known as the Czech Republic.

The documents concern Donald Trump and his first wife Ivana.

The president-elect of the US and his first wife were observed by the Czech Ministry of State Security, also known as the Stasi, in the 1970s and '80s. This is proved by documents from the security services’ archives in Prague that were presented at BILD’s request. Czech TV has also already reported on this case.

The CSSR Stasi’s files also contain a travel permit for Ivana Trump to leave Czechoslovakia.

Ivana comes from the former CSSR and used to regularly visit her now deceased father Milos Zelnicek in her home country.

In June 1977, an informant with the cover name “Lubos” reported that Ivana had married a man in Austria in 1968 and had worked there at a petrol station. After that, the informant claimed, she emigrated to Canada and married the American Donald Trump.

The dossier talks about a prenuptial contract that says he wants at least three children. If their marriage were to break down, Trump expects a compensation of one million dollars for Ivana.

The spy writes that Trump’s company is absolutely safe, economically speaking, since it receives commissions from the state. One other juicy detail: “Another advantage is the personal relationship with the American President and the fact that he is completely tax-exempt for the next 30 years.”

On October 21, 1988, a source with the cover name “Milos” reports that Trump is being put under pressure to run for the US presidency. Concerning a visit by Ivana to the CSSR, the source says that “any false step of hers will have incalculable consequences for her husband’s position, who intends to run for President in 1996.”

Even though it sounds utopian, Trump is allegedly convinced that he will be successful. However, his candidacy wouldn't happen for decades.

According to a report with the number 450/88, for the US election campaign in 1988, Trump donated 10,000 dollars each for the Democrats and the Republicans. The file says that Ivana Trump was convinced back then that Bush would win – and she was proven right.

An agent of the CSSR Stasi even travelled to the US in order to spy on Trump. In an “agency note” of 10 October 1989, a source called “A-Jarda” reports a visit by the delegation of an Agricultural Production Cooperative (APC) from the CSSR to Trump: “In the US, they were welcomed by one of the richest men in New York, Mister Donald Trump. He had them inform him extensively about the work of the cooperative and its further plans in the field of trade. At the end, he accepted an invitation to visit Slusovice (a town in the Czech Republic).”

Czech historian Tomas Vilimek told BILD: “An encrypted document from 1979 states that the phone calls between Ivana and her father were to be wiretapped at least once per year. Their mail exchange was monitored.” The Communist secret police even observed the Trump children’s visits to their grandfather. The informers noted that Ivana Trump spoke Czech with her children when they were in the US and noted who the friends and acquaintances of her family in the CSSR were.

Vilimek: “Ivana’s father was registered as a confidant of the StB. However, that does not mean he was an agent. The CSSR authorities forced him to talk to them because of his journeys to the US and his daughter. Otherwise, he would not have been allowed to fly.”
