The FBI amassed a dossier on the late journalist David Halberstam for more than two decades – keeping tabs on his reporting, tracking his marriage to a Polish actress and preparing background reports on the Pulitzer Prize winner for other federal agencies, documents show.

The feds appear to have paid particular attention to Halberstam in the mid 1960s when he was a New York Times correspondent in Poland during the Cold War – when that nation was closely aligned with the Soviet Union.

Halberstam married one of Poland’s top actresses, Elzbieta Czyzewska. He was expelled in 1967 for his coverage, including stories that cast doubt on public support for Poland’s Communist leaders.
