Four years ago I wrote about Henry Cejudo, who won a gold medal in freestyle wrestling at the Beijing Olympics. Henry's mother raised he and his six siblings in the US after coming here from Mexico as an undocumented migrant at the age of 14.
Now look at who is on Team USA in London this year.
Leo Manzano - who will compete for the U.S. in the 1,500 meter race - was born in the central Mexican town of Mojoneras. His parents moved 4-year-old Leo and his younger sister, Laura, to Texas’ Hill Country in 1989.
Marlen Esparza will be part of the Olympics debut of women's boxing. Her father immigrated from Mexico and her mother was born in El Paso.
Gymnast Danell Leyva won a bronze medal today in the men's all-around competition. He as born in Matanzas, Cuba and emigrated to the U.S. with his mother when he was 3. Danell's stepfather - who has been his coach and biggest supporter at the Olympics - came across the Rio Grande illegally.
Its obvious that these three young people are amazing athletes. But its also true that the years of hard work and sacrifice from not only each of them, but their families, is what the American Dream is all about. I'm proud to have them representing my country at the Olympics.
