I couldn't help but to think back to my classmates at Thomas Jefferson High School in San Antonio. They had the same talent, the same brains, the same dreams as the folks we sat with at Stanford and Harvard. I realized the difference wasn't one of intelligence or drive. The difference was opportunity.

My grandmother didn't live to see us begin our lives in public service. But she probably would have thought it extraordinary that just two generations after she arrived in San Antonio, one grandson would be the mayor and the other would be on his way - the good people of San Antonio willing- to the United States Congress.

I stand before you tonight as a young American, a proud American, of a generation born as the Cold War receded, shaped by the tragedy of 9/11, connected by the digital revolution and determined to re-elect the man who will make the 21st century another American century - President Barack Obama.

Donald Trump really has, truly has motivated the Latino community more than any other presidential candidate, I think, in generations, and motivated them in a negative way.

Donald Trump is just unfit, unprepared, just doesn't get it, shouldn't be the commander in chief of America.

Donald Trump ought to realise that being a president is different to being a candidate and that there is a responsibility that comes with the office.

In my mind, there's no question that Donald Trump has energized the Latino community more than any other presidential candidate. Unfortunately for him, he's done that in a negative way.
