Political journalist Ryan Lizza has accused his ex-fianceé, the acclaimed magazine writer Olivia Nuzzi, of “catastrophically reckless behavior” in a year-long affair with Robert F. Kennedy Jr. that led to the journalists’ breakup this summer,

Robert F. Kennedy Jr. was more obsessed with journalist Olivia Nuzzi than he admits and wanted to “possess,” “control,” and “impregnate” her, according to a new court filing by her ex-fiance, Ryan Lizza.

Nevertheless, the magazine and Nuzzi agreed that the best course forward is to part ways,” the publication said in a statement.
