A senior al-Qaida leader and son-in-law of Osama bin Laden, captured in Jordan in the past week, pleaded not guilty March 8 in federal court in New York to plotting against Americans in his role as the terror network’s top spokesman.

Sulaiman Abu Ghaith was brought into the largest courtroom at the federal courthouse shortly after 10 a.m. and entered the plea through a lawyer to one count of conspiracy to kill Americans in a case that marks a legal victory for President Barack Obama’s administration.
