Then she brought a US professor to court for libel because he provided a 50-page investigative report on the Thesis Gate, and US continue to kept quiet—Because a call for a petition on the White House petition page failed.
Then she had police harass another US citizen who posted a video on the Thesis Gate, and US still kept quiet—Because the American Institute in Taiwan was not reported to be intervening.
Soon there will be no remedy left for US to take.
