HOUSTON -- A Houston billionaire is fighting back against guns with a very large donation.
Lawyer Steve Mostyn gave $1 million to Gabrielle Giffords’ new gun control organization.
This week, Giffords and her husband, retired astronaut Mark Kelly, launched Americans for Responsible Solutions.
The former Arizona congresswoman was critically injured during the January 8, 2011 Tucson mass shooting.
There are reports that Kelly called Mostyn after last month's shooting at Sandy Hook Elementary School in Newtown, Connecticut.
