A Trump-obsessed Chinese national was convicted Wednesday of sneaking into the president’s Mar-a-Lago club in Florida.

Jurors found Yujing Zhang, 33, guilty of trespassing and lying to Secret Service agents — after four hours of deliberations and an unusual two-day Fort Lauderdale federal court trial initially delayed over Zhang’s lack of underwear.

Zhang, who remains in custody, showed no emotion as the verdict was read but smiled as she was led out of court.

Prosecutors said Zhang was wearing a gray evening gown when she waltzed into the Palm Beach resort on March 30 and started taking pictures. She had lied to a Secret Service agent to gain entrance to the swanky club, with prosecutors saying she claimed she was a relative of an actual club member.

But a receptionist soon grew wary. “As soon as she entered the lobby, you could see that she was fascinated, she was looking around,” the worker, Ariela Grumaz, said, adding that Zhang seemed “weird and strange.”

Zhang told Grumaz that she had paid $20,000 to attend a Chinese-American United Nations friendship event that day, which had actually been canceled.

That’s what prompted Grumaz to flag a Secret Service agent to keep an eye on Zhang.

After the agent pulled her outside and searched her phone, she became “aggressive,” according to testimony.

Prosecutors said Zhang was kitted out with electronics including four cell phones, a laptop and an external hard drive. Agents who searched her nearby hotel room found $8,000 in cash and spy-like gear, such as a device to detect hidden cameras, and numerous credit and debit cards.

Zhang, who entered the US on a 10-year visa that she obtained in 2016, also had two passports. Her arrest prompted a probe into whether she was a Beijing spy, but she faced no espionage charges.

Prosecutors offered no explanation in court for her motives.

She acted as her own attorney at trial after firing her public defenders in June.

She now faces up to six years in prison when she’s sentenced Nov. 22.

Prosecutors and the public defenders on standby during the trial declined to comment.
