Input: Attorney Armstrong Graham said Mohammed Zazi was asked about his son's history. Graham declined further comment.
 Asked by reporters if his son was frightened  Mohammed Zazi said: "If you don't have anything  why would you be scared?" He refused to answer more questions.
 Najibullah Zazi has already undergone hours of questioning this week  and his apartment and his uncle and aunt's home in suburban Denver have been searched.
 Folsom told The Denver Post the agents aren't repeating questions to Zazi but are asking different things.
 Najibullah Zazi is a driver for an airport shuttle service in Denver. Authorities say he rented a car and drove from Denver to New York  crossing into Manhattan the day before the anniversary of the Sept. 11  2001  terror attacks.
 He was stopped in what was described as a routine stop at the George Washington Bridge before he was allowed to go free.
 A relative said Zazi drove because he wanted to see the American countryside. Zazi said he went to New York to resolve some issues with a coffee cart he owns in Manhattan  but officials suspected that something more sinister might have been in the works.
 FBI agents and police officers with search warrants seeking bomb materials searched three apartments and questioned residents in the neighborhood in Queens where he was staying.
 Folsom said Zazi  24  was born in Afghanistan in 1985  moved to Pakistan at age 7 and emigrated to the United States in 1999. Zazi's aunt had said earlier that he was born in Pakistan and grew up in Queens  New York City.
 Folsom said Zazi has returned to Pakistan four times in recent years: in 2004 because his grandfather was sick and dying  in 2006 to get married  and in 2007 and 2008 to visit his wife.
