Task: Question Answering
Input (English): Passage: The day after the Young Turks' press conference, Taylor privately met Khánh at the latter's office. He complained about the dissolution of the HNC and said it did not accord with the values of the alliance and the loyalty Washington expected of Saigon. He added that the US could not cooperate with two governments at once: a military regime that held power while a civilian body took the responsibility. Khánh testily replied that Vietnam was not a satellite of the US and compared the situation to the US support of the successful coup against Diệm, saying that loyalty was meant to be reciprocated. Khánh had hinted that he felt the Americans were about to have him deposed like Diệm, who was then assassinated, but this rankled Taylor, who had argued against the regime change. Taylor then bemoaned Khánh, saying he had lost confidence in the Vietnamese officer, recommending Khánh resign and go into exile. He also said military supplies currently being shipped to Vietnam would be withheld after arriving in Saigon and that American help in planning and advising military operations would be suspended.Khánh bristled and said "You should keep to your place as Ambassador ... as Ambassador, it is really not appropriate for you to be dealing in this way with the commander-in-chief of the armed forces on a political matter, nor was it appropriate for you to have summoned some of my generals to the Embassy yesterday." He threatened to expel Taylor, who responded by saying a forced departure would mean the end of US support. However, Khánh later said he was open to the possibility of going abroad and asked Taylor if he thought this would be good for the country, to which the ambassador replied in the affirmative. Khánh also said he took responsibility for his generals' actions, and expressed regret at what they had done. Khánh then ended the meeting, saying he would think about his future.Later, Khánh phoned Taylor from his office and expressed his desire to resign and go abroad along with several other generals, asking for the Americans to fund the travel costs. He then read Taylor the list of generals for whom arrangements needed to be made, and asked the ambassador to repeat the names for confirmation. Taylor did so, unaware Khánh was taping the dialogue. Afterwards, Khánh played the tape out of context to his colleagues, giving them the impression Taylor was calling for their expulsion from their own country. Khánh then asked his colleagues to participate in a campaign of fomenting anti-American street protests and to give the impression the country did not need Washington's aid. A CIA informant reported the recent arguments with Taylor had incensed the volatile Thi so much that he had privately vowed to "blow up everything" and "kill Phan Khắc Sửu, Trần Văn Hương and Nguyễn Khánh and put an end to all this. Then we will see what happens.". 
Question: What is the full name of the person who threatened to expel Taylor?
