This was Norman's second visit to the center, which has taken in thousands of immigrants over the past several weeks, KGBT-TV reported.
Norman's charity work at the border began last summer when he heard of the now-reversed "zero-tolerance" immigration policy that led to thousands of families being separated, CNN reported. He visited a Walmart in San Antonio and filled carts with toys, books and school supplies that he donated to children at detention centers.
"Everybody sees it. Everybody knows this is going on, so what are you going to do about it? You going to show up and put up or see it and shut up? Which one?” Norman told KGBT-TV. “I encourage everyone who is watching or paying attention, if you can get out here, do get out here for yourself. It's not something we kid around with. This is people's lives."
Norman has played for the Redskins since 2016, according to the team's website. He told KGBT-TV he plans to donate his game checks throughout the year.
