Usama bin Laden's son-in-law and Al Qaeda spokesman Sulaiman Abu Ghaith has plead not guilty to the charge of conspiracy to kill Americans in a New York federal court.

David Lee Miller reports live from the scene that this was Ghaith's first-ever court appearance. He was arrested shortly before midnight on February 28th overseas and he arrived in the United States on March 1st. His next court appearance will be in April.

A chilling detail, Miller points out, is

that Ghaith warned that there would be more attacks in the United States.
