The FBI released the documents in a 43-page filing seeking the court's permission to bring new charges against Keyser in what a government prosecutor has called an "espionage-related case."
The documents produced by the FBI allegedly demonstrate that Keyser provided "extensive" information to Cheng that "was valuable to her work as an intelligence officer," the FBI says. The bureau also says the information proves Keyser was not honest in his dealings with investigators in the case.
Keyser's lawyer, Robert Litt, rebutted those contentions.
"Mr. Keyser denies that he was ever acting on behalf of Taiwan's intelligence agency," he said. "The government's submission contains numerous inaccuracies and misinterpretations of innocuous facts."
Keyser was arrested after having lunch at a suburban Washington restaurant with Cheng and her boss, Huang Kuang-hsun (黃光勳), reputedly the National Security Bureau's (NSB's) top intelligence operative at the Taipei Economic and Cultural Representative Office (TECRO), during which Keyser was seen handing them an envelope.
The FBI had followed Keyser for some time, observing his relationship with Cheng between 2002 and 2004, after Keyser allegedly failed to report to his superiors a rendezvous he had in Taipei with Cheng the previous September.
In a plea bargain reached last December, Keyser pleaded guilty to three charges related to that incident, failing to report his relationship with Cheng and the possession of thousands of classified and secret documents, found during an FBI raid of his home. In return for guilty pleas, the FBI said it would not pursue additional charges.
Revisiting the deal
However, in a court hearing before District Court Judge T.S. Ellis last month, the prosecution asked the judge to be released from the agreement, alleging that Keyser did not keep his end of the bargain, but lied to investigators in subsequent questioning.
Litt, in a 29-page rebuttal filed with the court on Friday, said that all the information in the latest FBI filing was known to the agency before it agreed to the plea bargain. It also asserted that Keyser's constitutional right to a fair trial was being violated because the FBI has refused to show him much of the information on which its contentions are based, most of which is secret and cannot be shared with him.
The defense response refers to "the government's stubborn and erroneous belief that Mr. Keyser was a spy."
It said that Keyser "disclosed no classified information to Ms. Cheng or her superior, Mr. Huang, and his communications were all in furtherance of US government interests."
Sexual allegations
In the new memorandum, the FBI for the first time specifically alleged that Keyser and Cheng engaged in sexual relations. Although the FBI says Keyser denied that Cheng had offered "sex for information," the memorandum cites a series of encounters in Keyser's car, Cheng's apartment and elsewhere.
At one point, after the pair spent 20 minutes in Keyser's car in a side street in which Cheng's head was said to be "leaning toward the defendant and disappearing in front of him," Keyser allegedly said in an intercepted cellphone call to Cheng, "The food was good, the wine was good, the champagne was good and you were good."
At another point, Keyser drove Cheng home and stayed in her apartment for nearly an hour close to midnight. He told investigators that in the apartment "she removed all of her clothes and he touched her all over her body," but said that they did not have sex.
The FBI also allegedly observed the couple in his car on a reclined seat moving below the sight line of the door frame. Regarding one instance, Keyser contended the two did not remove their seat belts and engaged only in "heavy petting."
In the cables, which were marked "secret" and sent in Chinese from Cheng at TECRO to the NSB headquarters, Cheng recounted Keyser's analysis, comments and details of US policy toward Taiwan and of his discussions with leaders, including Chinese President Jiang Zeming (
The cables also dealt with the runup to President Chen Shui-bian's (
One cable discloses that the State Department wanted to send Deputy Assistant Secretary of State Randy Schriver to greet Chen at the airport during the New York transit, but that Assistant Secretary James Kelly blocked the move, feeling that Taiwan would misconstrue Schriver's appearance as a sign that the US approved of Chen's constitution and referendum plans.
Prosecutors say that Keyser lied in his statements to investigators and failed to fully cooperate with them, which they say is grounds for freeing the government from its plea bargain obligations.
One e-mail indicates that Cheng may have been trying to recruit a former State Department official as a spy and that Keyser seemed to be providing information about him.
That person, who was described as having been frustrated by the State Department and later becoming a think tank academic, had his name blacked out in the publicly released version of the e-mail.
Taipei has once again made it to the top 100 in Oxford Economics’ Global Cities Index 2025 report, moving up five places from last year to 60. The annual index, which was published last month, evaluated 1,000 of the most populated metropolises based on five indices — economics, human capital, quality of life, environment and governance. New York maintained its top spot this year, placing first in the economics index thanks to the strength of its vibrant financial industry and economic stability. Taipei ranked 263rd in economics, 44th in human capital, 15th in quality of life, 284th for environment and 75th in governance,
The Sports Administration yesterday demanded an apology from the national table tennis association for barring 17-year-old Yeh Yi-tian (葉伊恬) from competing in the upcoming World Table Tennis (WTT) United States Smash tournament in Las Vegas this July. The sports agency said in a statement that the Chinese Taipei Table Tennis Association (CTTTA) must explain to the public why it withdrew Yeh from the WTT tournament in Las Vegas. The sports agency said it contacted the association to express its disapproval of the decision-making process after receiving a complaint from Yeh’s coach, Chuang
Control Yuan Secretary-General Lee Chun-yi (李俊俋) tendered his resignation last night, admitting that he had misused a government vehicle, as reported by media. His resignation was immediately accepted by the Control Yuan. In a statement explaining why he had resigned, Lee apologized for using a Control Yuan vehicle to transport his dog to a pet grooming salon on May 20. The issue first came to light late last month, when TVBS News reported that Lee had instructed his driver to take the dog to the salon. The news channel broadcast photos that it said were taken by an unnamed whistle-blower, which purportedly showed the
A former officer in China’s People’s Liberation Army (PLA) who witnessed the aftermath of the 1989 Tiananmen Square massacre has warned that Taiwan could face a similar fate if China attempts to unify the country by force. Li Xiaoming (李曉明), who was deployed to Beijing as a junior officer during the crackdown, said Taiwanese people should study the massacre carefully, because it offers a glimpse of what Beijing is willing to do to suppress dissent. “What happened in Tiananmen Square could happen in Taiwan too,” Li told CNA in a May 22 interview, ahead of the massacre’s 36th anniversary. “If Taiwanese students or
