FBI testimony
In June 2021, FBI agent Kujtim Sadiku admitted in a testimony that he falsely accused Hu of being a spy, baselessly implicated him as a Chinese military agent to UTK, and used false information to put him on the Federal No Fly List. The agent also stated he attempted to have Hu spy for the United States. Hu refused, leading to FBI agents stalking and harassing him for more than two years.[5] According to Sadiku, he got a tip that Hu might be a spy but cannot remember where he got that information. He did a Google search of Hu in March 2018, which turned up a couple of press releases in Chinese with one including a photograph of Hu. Sadiku then proceeded to use Google translation to do further research. The app made an error in translating Hu's forename in the photo caption. The translation of two documents described Hu obtaining a 2012 "short term" award to teach at Beijing University for 20 hours annually through China's Long-Term Thousand Talents Program as a visiting scholar. Sadiku investigated him based on his involvement in the program, which he described as benefiting the Chinese military. He opened up an economic espionage case because the US government believes the program aims at acquiring information and technology from the US. When Sadiku confronted Hu, Hu said that those who agreed to spy for China were "cheaters," and that he was not involved in any espionage. Sadiku offered Hu to spy for the US using his part-time work at Beijing University as cover, but Hu refused, stating that he was too afraid. Hu then sent Sadiku an email informing him that he would not go to China. Despite no longer believing Hu was a spy, Sadiku ordered a surveillance team to spy on Hu and his eldest son, then a freshman at UT, for the next 21 months. A group of six or seven agents followed him to work, to school, to the grocery, and even went through his trash. They found no evidence of espionage, but the FBI persisted in building up a case against Hu, resulting in the fraud charges. Sadiku called it Operation Chelsea Dagger.[6][7]
