Trevor Kincaid, McCaskill communications director: "As I'm sure you're aware, the provisions of this legislation are in flux. Claire wants to make sure we can catch the frauds and cheats, she also has real concerns about limiting the freedom of the internet. She's heard from constituents on both sides and is tracking the process -- hoping to see provisions finalized in a way that recognizes both needs. My concern right now, as I'm sure is yours, is making certain that when people contact our office to share their views they are doing so with the right information. Something that is currently being prohibited by the status on your website."

Editor's note: McCaskill's position was labeled as "supporter" because of her co-sponsorship of PIPA's precursor, the Combating Online Infringement and Counterfeits Act. It has been changed to "Undecided" now that we have a statement from her office regarding her deliberations on PIPA.
