Shahzad sat on the defense table beside his attorney Julia Gatto and said 'yes' when asked to confirm the accuracy of a financial statement.
He has been cooperating with the authorities, through out the process. “Shahzad...has provided valuable intelligence from which further investigative action has been taken," said Preet Bharara, the attorney before hearing.
