Zhang reportedly told conflicting stories about her reasons for wanting to enter the club, including wanting to attend a nonexistent event.

Zhang was not on the radar of federal authorities before her arrest, according to the Herald.

But since the incident, investigators with the FBI-led Joint Terrorism Task Force in South Florida have focused their resources on determining her connection, if any, to possible Chinese intelligence operations.

The investigation is also looking into Florida entrepreneur Li "Cindy" Yang, the Herald reported.

Yang made national headlines after New England Patriots owner Robert Kraft was charged with allegedly soliciting prostitution at a massage parlor she founded.

Yang has reportedly promoted events at the club to Chinese executives hoping to get an audience with Trump and those close to him, according to the newspaper.

The report comes the same day Senate Democrats asked the FBI to investigate possible security risks at Trump’s properties in the wake of Zhang’s arrest.
