McGraw said in a statement on Thursday there is no contradiction between gun ownership and supporting Sandy Hook Promise.
"Let me be clear regarding the concert for Sandy Hook given much of the erroneous reporting thus far. As a gun owner, I support gun ownership," he said. "I also believe that with gun ownership comes the responsibility of education and safety — most certainly when it relates to what we value most, our children. I can't imagine anyone who disagrees with that.
"The concert is meant to do something good for a community that is recovering," McGraw said.
McGraw got involved in the concert because the fiddle player in his band is a friend of one of the parents who lost a child in the Newtown shootings.
