Thank you, Mr. Chair.
Thanks very much for being here.
The first question I want to ask has two parts.
My feeling is that when we give such expansive, unprecedented powers to national security agencies, there has to be a need. First, do you believe that they need to demonstrate that need and that the burden of proof is on them? Second, has CSIS, among others, done that, in your view? The question is to both of you.
