Thank you very much.
First, let me thank the witnesses for joining us and for sharing their expertise with the committee. I hope to get through a number of questions here, so bear with me.
We've heard from various privacy experts who have talked a lot about whether or not the data that was sent to the government met the necessary criteria for it to be truly aggregated and de-identified. The government's response largely has been to just trust them on that front. From both of your perspectives, starting with Dr. Geist, do you believe the government met the criteria to ensure that the data was in fact properly de-identified and aggregated and could not be reidentified?
