Romo, from Brawley in Imperial County, about 30 miles north of the Mexican border, has worn his Mexican-American heritage with pride before, according to multiple reports. In the past, he's worn a shirt that said "Made in the USA with Parts From Mexico," the newspaper reported.
Romo did not mention the shirt in his remarks at the podium in front of City Hall on Wednesday. Not directly, anyway.
"Look at the diversity," he said, looking out over the crowd. "The different faces from different places, the different strokes."
"We all had one, how do you say, dream," he said. "You should be proud. ... I am very proud."
The shirt is now a hot item on eBay and other online retailers.
