Thank you. Tonight I have the honor of introducing you to our keynote speaker, my twin brother Julián Castro.

As you can imagine, this is a very special moment for our family. For each of us, the places that we call home shape our character, inform how we see the world and inspire our imagination.

Julián is a proud Texan. For 18 years we shared a small room and big dreams in our neighborhood on the West Side of San Antonio. Our hometown is a beautiful place, a place of hardworking, humble folks who grind out a living by day and go home and say prayers of thanks to God at night.

Since becoming mayor in 2009, Julián has worked tirelessly to pursue policies that honor the aspirations of the people he represents. I'm proud that my brother has achieved his dreams, but I'm even more proud of the work he's done to help others achieve theirs. Today, San Antonio is our nation's seventh largest city, a city on the rise that looks like America tomorrow.

Julián is a dedicated husband to his wife Erica, a public school teacher, and a wonderful father to his three-year-old daughter, Carina.

With much love and pride I present to you my best friend and my brother, Mayor Julián Castro.
