Transcript for JJ Watt raises Harvey fundraising goal to $10M
We are back now with the outpouring of support for all those impacted by hurricane Harvey and J.J. Watt, I'm telling you, T.J., that Houston Texan star, he's raised the bar. He is a three-time defensive player of the year in the NFL. What we would call the stud out in the field. Right. It does not matter what he does the rest of his career on the field, it does not matter what he does the rest of hit career for his Houston team, it will all pale in comparison to what he has now done for the Houston community. Uh-huh. Reporter: J.J. Watt, star defend defender is taking to social media to raise money for hurricane Harvey relief efforts. It's hard to not be able to help. Reporter: Starting with his own $100,000 donation he challenged his followers to match it and raised over $500,000 in less than a day and after tackling that goal he raised the bar higher. I've pupped it to 1.5 million. Reporter: And higher. $2 million. Reporter: Now after raising over $9 million he is setting his biggest goal yet. Everything is bigger in Texas and raising it to $10 million. Reporter: Money is pouring in from more than 6,000 donors. On Tuesday he told us it's the small donors making the biggest difference. The beauty of it all it's not necessarily big donations coming in, $5 here, $10 here, people from all over the country giving what they can. Not necessarily big donations, it's really a crowd funding effort and that's so incredible to watch. It won't be a one-week thing but a long-term relief effort and it's cool to see how many are stepping up. Reporter: Some other celebrities also stepping up. Kevin hart. My Harvey hurricane donation site is now live. It's set up and shouts out to J.J. Watt. Reporter: Sandra bullock and Leonardo Dicaprio and Dwayne "The rock" Johnson. We all want to step up to the plate. Reporter: All making big donations encouraging others to do the same. Keep in mind here, folks, he started with a goal and said I'll donate $100,000. Can you all match it? That was done in two hours. 200,000, a million, 1.5, 3, 5, 8, 9, now it's up to 10 million. There's probably no doubt it will hit 10 million even as we speak. He's gotten a couple big ones. A million dollar from Walmart but most of them 20 to $100 from a lot of individuals just wanting to -- It adds up. They trust him. That's the thing. He's such a likable -- J.J. Watt said do it -- it's going directly to the cause. Such an impressive. En the donations for our day of giving are already pouring in as well.
