Ansari told the local daily that she was unaware that the Alizotis did not make it to the flight until she landed in Atlanta.In an email to the newspaper, the president of Zubaidah's school [Webb School] Michael McBrien said that "We have no information regarding their status in Turkey other than what has been reported in the Knoxville News Sentinel. We are keeping Zubaidah and her family in our thoughts and prayers, and we hope for their speedy and safe return. And we’re looking forward to welcoming Zubaidah back to campus."Meanwhile, the Knoxville Mayor Madeline Rogero and Representative John J Duncan Jr's staff have taken notice of the incident and are working for solutions."I saw the Facebook posts about the Siddiqi family's situation, and I was concerned," the Mayor said in a statement. "I contacted the offices of Congressman Duncan and Senators Alexander and Corker, and they all responded promptly and promised to reach out to the Siddiqis. I have heard from Sabrina Siddiqi that she has heard from them, and she appreciates the support."According to Jesse Mayshark, the mayor's spokesperson, Senator Bob Corker and Lamar Alexander were contacted on Monday, to help in the matter.When approached by KnoxNews, Press Secretaries for Governor Bill Haslam and Alexander acknowledged the news but did not comment on it.According to the US Transportation Security Administration, the Knoxville resident could not board the flight because the airliner did not forward necessary information to the department in time."International carriers are tasked with providing security information to the federal government before a passenger can fly into the United States," TSA spokesperson Sari Koshetz said in an emailed statement. "That did not happen in this case."While the US Customs and Border Protection also denied involvement. A spokesperson for the department said that the agency did not prevent Alizoti from boarding the plane, the daily reported.Turkish Airlines representatives did not return emails from the newspaper requesting comment on the matter.Despite the inconvenience, Siddiqi said in another post that "I (still) believe in America".[fbpost link="https://www.facebook.com/sabrina.s.siddiqi/posts/10211087198148204"]
