In October 1990, Trump's 63-year-old father, Miloš Zelníček, died suddenly from a heart attack. According to "The Guardian", her father was an informer for Czechoslovakia's Státní bezpečnost (StB) intelligence service who relayed information from his daughter, including a prediction that George H. W. Bush would win the 1988 presidential election. Despite their marital troubles and pending divorce, Ivana stood side by side with Donald Trump at her father's funeral in Zlín held in November 1990. The service was also attended by Jaroslav Jansa, secret collaborator to the StB.
