Linda Sun, a former aide to New York governors, was accused of selling her influence to the Chinese government. Sun pleaded not guilty to charges that she failed to register as an agent of a foreign government, conspired with her husband to launder money and helped people commit visa fraud to enter the U.S. illegally. A December trial ended in a mistrial when a federal jury could not reach a unanimous verdict.

Charles Burnham, Pauken's defense lawyer, said in a statement that, by his guilty plea, Pauken "has accepted responsibility for working as an agent of the People's Republic of China without first completing certain required U.S. Government forms."

Burnham said Pauken had hoped his work would "promote peaceful relations and advance the cause of religious freedom in China."

Pauken was arrested in February after arriving in Washington from China. He met with someone who had sought a job in the Trump administration to provide that person with a SIM card and offer $10,000 to write reports to be read by Chinese President Xi Jinping, according to the affidavit.

He appeared to see himself as a middleman between Chinese agents and "human resources" who could provide classified information to Beijing, according to the affidavit. His lawyer didn't immediately respond to a message seeking comment.

Since at least 2019, Pauken had been working with Chinese agents, including "Cathy," who he believed to be working for China's security apparatus. Between 2019 and 2025, Pauken received $100,000 for the reports he provided to Cathy, in addition to paid trips to the U.S., the affidavit says. Cathy told him the reports were to be read by Xi.

Pauken was stopped by Customs and Border Protection agents when he returned to the U.S. in January 2025. In interviews with CBP and FBI agents, Pauken said he was meeting a person who was seeking a job in the Trump administration and would provide that person with a Samsung phone and a laptop computer. He said he was "80% sure" that person, if hired by the new administration, would provide classified information to Beijing, according to the affidavit.

U.S. agents let Pauken go and instructed him to carry on with his plans. Pauken's contact said in an interview that Pauken asked for open-source information but also indicated his clients in China frequently asked for more secretive information. That person indicated having no intention of working with Pauken, the affidavit said.
