As a part of preparing those lawsuits, learning about those lawsuits, I learned about the various nuclear issues in parts of the nuclear production process I guess you'd say.

Athletes, coaches and parents today are increasingly aware of the danger of concussion, and this awareness influences decisions about buying new and reconditioned football helmets.

They rushed to move it forward, uh, and then a lawsuit was filed and we spent many months litigating, rather than trying to come up with legislation and move forward on that front.

With existing technology, we can enforce airport security without sacrificing our personal privacy.

It's a national concern, I mean how we dispose of nuclear waste in a safe way, how we deal with this incredible amount of nuclear waste we have created over the years.

It's very, very difficult I think for us to have a transparent debate about secret programs approved by a secret court issuing secret court orders based on secret interpretations of the law.

I will never forget the debt we owe to those who have fought to keep America safe.
