Joseph Lieberman actually said...

I agree with you, Senator McCaskill, in your criticisms of the process. We have made mistakes. We are going to fix them.

I agree totally on the last point that all the steps that are occurring now... will be decimated if Iran goes nuclear.

it is unacceptable to us in terms of our security and our values that Iran obtain nuclear weapons.

Thanks to you and Senator McCain for convening this very important hearing.
