Chen was interviewed in her office by two security agents from the Department of Commerce. It was a 7-hour marathon interrogation with no food, water, or break after Chen had worked for half a day. The two agents told Chen that she could not tell this interview to anyone, and that she didn’t need a lawyer. Chen tried to collaborate and told the agents everything she knew. The agents failed to find any “spying” evidence. But they still claimed Chen was “lying” to federal investigators because Chen couldn’t quite recall some of the dates or events.
