The Chinese woman arrested at Mar-a-Lago who claims she paid $20,000 to a Chinese businessman in order to be there stayed at a Trump hotel property in Manhattan during two prior trips the U.S. Yujing Zhan, who was booked after being questioned for hours by Secret Service agents both inside and nearby the president's private club, was found to be in possession of nine USB drives, more than $8,000 in cash, and a thumb drive including malicious malware, according to court documents. She also had two passports on her, including one that had expired. Passport stamps reveal that she was admitted to the U.S. on four other occasions before the March 28, 2018 trip that preceded her arrest. A source familiar with her case told the Miami Herald that on two of those trips – in July 2016 and January 2017 – she stayed at a Trump hotel property in New York City. This means she would have been staying at either the Trump International Hotel and Tower, located at Columbus Circle, or the now renamed Trump Soho. Yujing Zhang was arrested with two passports, four cell phones, and a USB drive that a Secret Service agent found had malware when inserting it into his computer At the time of her arrest, Zhang told authorities she had been at Mar-a-Lago for an event, and had been invited by her associate Charles. Although there was no such event on the calendar, Chinese businessman Charles Lee had been promoting an event that had been cancelled for that same night. According to a flyer introduced as a defense exhibit, the event was to feature Elizabeth Trump-Grau, the president's sister. Zhang told the secret service she wanted to talk to Trump family members at the event. Her stays at a Trump hotels, which are open to the general public, on earlier visits could indicate a longer-term effort to interact with Trump's circle. According to immigration stamps on passports also introduced as evidence, she arrived in the country July 2016, in the heat of the presidential campaign. The next visit began January 03, 2017, just days before Trump's inauguration. Zhang's passport included stamps for the times she entered the U.S. Each of the trips appear to have lasted about 10 days. Other visits began December 2, 2017 and Sept. 14, 2018. Zhang entered the U.S. on a business visa that allowed her to make repeat trips to the country for a period of a decade. Zhang, who had a bond hearing in Florida Monday, entered the U.S. on a B-1/B-2 visa, according to documents released by the government. She has another hearing this coming Monday. Her visa allowed her to travel to the U.S. for a period ranging from 2016 through 2026. Those visas are designed for people who need to be in the country on a temporary basis, such as to attend a business conference, or to seek medical treatment. They allow for repeat visits. The visas do not require an employee sponsor, though it was not immediately known how Zhang, 32, was able to obtain her travel document. Two days after her most recent arrival, she was arrested after talking her way past security at the president's private club, where members pay a $200,000 initiation fee, and where Trump family members and top aides frequently spend weekends. According to a Secret Service affidavit, a club security person who spoke to her concluded she may have been related to a club member with the same name, although Zhang is one of the most common names in China. When she was at security, she also said she was there to go to the pool, although an agent noted in the affidavit that she had no bathing suit. She was arrested with two passports on her, one of which had expired in 2017. One of Zhang's passports expired in 2017 Her visa allowed Zhang to travel to the U.S. multiple times over a ten-year period The defense submitted a flyer touting a Mar-a-Lago event in Chinese and featuring a picture of President Trump's sister, Elizabeth Trump-Grau Zhang was charged with lying to investigators and entering a restricted area Zhang said she was at Mar-a-Lago to attend an event at the invitation of a man she identified as 'Charles' Zhang flew from Shanghai to Newark before dropping in on Mar-a-Lago She was arrested two days after entering the country Zhang's attorney, Robert Adler, on Monday presented a different sequence of events. He said his client wired $20,000 to a party organizer for access to Mar-a-Lago to attend what she thought was a party later that night – an event that earlier in the week was cancelled. Adler introduced a flyer for the event, which featured writing in Chinese as well as a photo of Elizabeth Trump-Grau, who according to the flyer was supposed to be there. The company where Zhang transferred the $20,000, the Beijing Peace and Friendship Management Consulting Co., Ltd., had also been used by Lee for a 2018 'Safari Night' party at the hotel, according to the Herald. The flyer had been posted on the web site of Cindy Yang, who formerly owned the Orchids of Asia Day Spa where New England Patriots owner Robert Kraft was arrested and charged with soliciting prostitution. It later emerged that Yang marketed Mar-a-Lago packages in China and has been pictured with Trump and a raft of Trump family members. Yang, 45, seen in foreground with President Trump and a guest at Mar-a-Lago in February at a Mar-a-Lago Super Bowl party President Donald Trump was at his nearby golf course when the Chinese woman was arrested with two passports, four cell phones and computer drive with 'malware' The White House is downplaying a security breach at Mar-a-Lago following the arrest of Yujing Zhang, a Chinese woman, who tried to enter the club over the weekend In this artist sketch, a Chinese woman, Yujing Zhang, left, listens to a hearing Monday, April 8, 2019, before federal Magistrate Judge William Matthewman in West Palm Beach, Fla. Secret Service agents arrested the 32-year-old woman March 30 after they say she gained admission by falsely telling a checkpoint she was a member and was going to swim In addition to the four cell phones on her, Zhang had a stash of cash at her hotel room as well as a signal detector that can be used to locate hidden cameras. Adler said sources in China sent his office a receipt from what appeared to be wire transfer for $20,000 to businessman Charles Lee, the alleged organizer of the cancelled party. House Oversight Chairman demanded a security briefing following the apparent intrusion. He spoke to the departing head of the Secret Service, Randolph 'Tex' Alles, before the White House announced he was resigning, in a piece of a homeland security purge. Cummings told DailyMail.com Tuesday the agency is still looking into the matter. 'They're still doing their own research.,' he said. Also included in defense exhibits on file with the court are numerous pictures of Charles Lee. Lee has been pictures twice with Cindy Yang. Earlier court documents revealed that when Zhang was questioned by the Secret Service, she claimed a person she identified only as 'Charles' had told her to attend a United Nations Chinese Friendship Association event at the club. The event had been cancelled, although it had originally been scheduled for the day she was there. In court, Adler argued that his client hadn't done anything wrong by being at Mar-a-Lago. Trump stayed there that weekend but had been golfing at the time. 'What did she do that was wrong?' Adler said, the New York Times reported. 'What she did was the equivalent of saying, 'My name is Smith, I'd like to use the pool.' All rights reserved for this news site dailymail and under his responsibility
