Over the weekend, a Chinese woman named Yujing Zhang passed through a Secret Service security checkpoint at Mar-a-Lago, a private resort owned by President Donald Trump, and gained access to the pool, claiming she was there for a swim. At the time, Trump was playing golf while the first lady and other members of his family were present at the resort. Zhang’s story seemed odd and drew extra suspicion from Secret Service agents.

The Secret Service asked to speak with her. Upon searching her belongings they found no swimming attire, but found that she did have a laptop, four cell phones, an external hard drive, and a thumb drive among her belongings. She was then interviewed by a division within the Secret Service known as Protective Intelligence or PI. “The main focus of PI interviews is on opportunity, means, motive, and intent. This division was stood up after the Kennedy assassination and further enhanced after the Reagan attempt,” former Secret Service Agent Bill Gage told NEWSREP.

Now Zhang has changed her story, relating to Secret Service agents that her friend Charles had invited her to a United Nations Chinese-American friendship event. No such event existed, but a man named Charles Lee is known to run the United Nations Chinese Friendship Association, which is not actually affiliated with the United Nations—in fact, it promotes the Chinese communist party, according to the Miami Herald. The fictional event that Zhang claimed to have been invited to was an event advertised on social media by Li Yang, a woman who ran a “massage parlor” in South Florida.

In a recent law enforcement sting, 25 men were arrested for allegedly soliciting prostitution at the Orchids of Asia massage parlor, including Robert Kraft, the owner of the New England Patriots. The women who worked at the parlor may be designated by law enforcement as victims of human trafficking.
