My Marine experience helped shape who I am now personally and professionally, and I am grateful for that on an almost daily basis.

I'm not in the being-annoyed business.

I'm not saying Senator Mitchell's report is entirely wrong. I am saying Brian McNamee's statements about me are wrong. Let me be clear: I have never taken steroids or HGH.

A debate has one purpose, one purpose only, and that is to facilitate the exchange of ideas directly between two candidates, and that's it.

I believe an invitation from the Commission on Presidential Debates is similar to a draft notice - a civic responsibility.

Those who know me know I won't hesitate to turn around and point someone out.

Most of the gaffes I've made have not been funny - they've been stupid.
