LOS ANGELES (Reuters) - A U.S. citizen sentenced last year to 12 years in a Vietnamese jail for “attempting to overthrow the state” spoke of his 27-month detention at a Zoom news conference on Wednesday, after he was released and returned to his home in California last week. Michael Nguyen, who was born in Vietnam in 1964 and lived in the United States since childhood, was detained in July 2018 on suspicion of anti-government activities, including alleged incitement of protesters to attack government offices with Molotov cocktails and slingshots, state media reported at the time. “I was essentially kidnapped, myself and three others, taken off a bus,” Nguyen, the father of four daughters, said of his detention. “No reason was given to me. No credentials were presented to me. I was blindfolded, handcuffed and put into a car by people in civilian clothes.” He said he was interrogated “for 16 hours at a time for days.” His trial came nearly a year after his capture, during which time he had no access to a lawyer, Nguyen said. The day before the trial he was provided a public defender “who was given a stack of paper more than 12 inches tall.” “They had written out a statement for me to sign and the public defender’s main job was to get me to sign a statement of words that were not even my own,” Nguyen said. When he tried to speak, he was stopped in court. “They silenced me,” he said.Nguyen’s wife, Helen, attended U.S. President Donald Trump’s State of the Union speech last year as a guest of U.S. Representative Katie Porter, a California Democrat who hosted the Zoom news conference. His release comes ahead of Vietnam’s announcement this week that U.S. Secretary of State Mike Pompeo will visit Vietnam on Thursday and Friday as part of a tour of Asia.
