Thank you for stating so well what I was thinking.
For reference, the firm representing PragerU is Brown George Ross. Former CA Governor Pete Wilson was a part of the team in court today but from what I could tell Peter Ross was the lead attorney representing PragerU today. His bio can be found here: http://www.bgrfirm.com/attorneys/peter-ross/
Thank you for the link!
Additional research indicates that this is the attorney representing PragerU at the Ninth Circuit earlier today: http://www.bgrfirm.com/attorneys/peter-obstler/
