We've seen tremendous progress in many ways under President [Barack] Obama. I mean, if we think about where the economy was when he got in - you know, we were losing more than 700,000 jobs a month. The unemployment rate was skyrocketing. And now it's at under 5 percent, so there is a lot of progress that has happened.

The American dream is not a sprint, or even a marathon, but a relay. Our families don't always cross the finish line in the span of one generation. But each generation passes on to the next the fruits of their labor. My grandmother never owned a house. She cleaned other people's houses so she could afford to rent her own. But she saw her daughter become the first in her family to graduate from college. And my mother fought hard for civil rights so that instead of a mop, I could hold this microphone.

Opportunity today, prosperity tomorrow.

My family's story isn't special. What's special is the America that makes our story possible. Ours is a nation like no other, a place where great journeys can be made in a single generation. No matter who you are or where you come from, the path is always forward.

Now, in Texas, we believe in the rugged individual. Texas may be the one place where people actually still have bootstraps, and we expect folks to pull themselves up by them. But we also recognize there are some things we can't do alone. We have to come together and invest in opportunity today for prosperity tomorrow.

My hope is Donald Trump will focus on building bridges instead of walls.

With the opportunity we build today for a shared prosperity tomorrow, America will prevail. It begins with re-electing Barack Obama.
