The father of one al Qaeda's leading recruiters is seeking to challenge the Obama administration's decision to place his son on a federal hit list.

Nassar al Awlaki wants his son Anwar al-Awlaki removed from a list of people who may be killed or captured by the Central Intelligence Agency or the U.S. military.

However, Anwar's designation as a specially designated global terrorist makes it illegal for lawyers to provide representation for his benefit without obtaining a license.
  
The American Civil Liberties Union and the Center for Constitutional Rights, which are representing Nasser al Awlaki, have gone to court to challenge the requirement.

Anwar al-Awlaki, the U.S.-Yemeni citizen dubbed as al Qaeda's top English-language internet recruiter, is believed to be hiding in Yemen.
