she had fled to the Netherlands), and in another letter her father denounced her. Christopher DeMuth, president of the American Enterprise Institute (AEI), said that the asylum controversy would not affect the appointment. He stated that he was still looking forward to "welcoming her to AEI, and to America." On 27 June 2006, the Dutch government announced that Hirsi Ali would keep her Dutch citizenship. On the same day a letter was disclosed in which Hirsi Ali expressed regret for misinforming Minister Verdonk. Hirsi Ali was allowed to retain her name. Dutch immigration rules allowed asylum seekers to use grandparents' names. Her grandfather had used the last name Ali until his thirties and then switched to Magan, which was her father's and family's surname. This grandfather's birth year of 1845 had complicated the investigation. (Hirsi Ali's father Hirsi Magan Isse was the youngest of his many children and born when her grandfather was close to 90). Later the same day Hirsi Ali, through her lawyer and in television interviews, stated that she had signed the resignation letter, drafted by the Justice Department, under duress. She felt it was forced in order for her to keep her passport, but she had not wanted to complicate her pending visa application for the US. she still carried her Dutch passport. In a special parliamentary session on 28 June 2006, questions were raised about these issues. The ensuing political upheaval on 29 June ultimately led to the fall of the second Balkenende cabinet. Life in the U.S. In 2006, Hirsi Ali took a position at the American Enterprise Institute in Washington, D.C.; as the Dutch government continued to provide security for her, this required an increase in their effort and costs. On 17 April 2007, the local Muslim community in Johnstown, Pennsylvania protested Hirsi Ali's planned lecture at the local campus of the University of Pittsburgh. Pittsburgh imam Fouad El Bayly said that the activist deserved the death sentence but should be tried and judged in an Islamic country. On 25 September 2007, Hirsi Ali received her United States Permanent Resident Card (green card). In October 2007, she returned to the Netherlands, continuing her work for AEI from a secret address in the Netherlands. The Dutch minister of Justice Hirsch Ballin had informed her of his ruling that, as of 1 October 2007, the Dutch government would no longer pay for her security abroad.
