Brian Dooley, Senior Director, Human Rights First:

"Can you tell us how you have investigated the allegations of torture made in May, what your findings were and what action you have taken?

Can you also explain why Ebtisam Al Saegh has not been allowed access to a lawyer in the last 10 days, or why her family have not been permitted to see her?

Will you commit to investigating all allegations of mistreatment or torture committed by the NSA and hold those responsible to account?"
