Osama bin Laden's son-in-law pleaded not guilty to charges in a New York court today that he conspired to kill Americans as part of the al Qaeda terror network.
Sulaiman Abu Ghaith appeared in videos sitting next to bin Laden after the 9/11 attacks and he issued a warning.
"We advise them not to fly in planes or live in high towers. The storm of planes will not stop, there are thousands of young muslims who are desire martyrdom in the path of Allah,"Â Sulaiman Abu Ghaith said.
Not everyone is happy to see this suspect in a New York court.
Outfront tonight: Cliff May, President of the Foundation for the Defense of Democracies, and David Frum, former Speechwriter for President George W. Bush.
