A federal investigator took the stand for the second day Tuesday in the terror trial of alleged al-Qaeda supporter Mustafa Kamel Mustafa.
Lawyers for the Egyptian cleric are cross examining George Corey as jurors are being shown several videos.
The footage shows Mustafa, also known as Abu Hamza al-Masri, doing interviews and giving speeches.
In the tapes, Mustafa approved of both the September 11th attacks and the 2000 bombing of the USS Cole in Yemen, which killed 17 American sailors.
But his lawyers argue that in the videos, their client also says the training camps he's accused of setting up are all about self-defense.
Prosecutors allege Mustafa set up those camps to train aspiring terrorists.
His lawyers say their client will take the stand next month.
