Hutchison said Friday she will lead a bipartisan group from Congress in filing an amicus brief in the case McDonald v. the City of Chicago. She is trying to unseat fellow Republican Gov. Rick Perry, another gun rights advocate.
Hutchison says she wants the Supreme Court to rule that gun ownership is an individual right that should apply at the state level.
She also said she agrees with a Texas law passed in 2007 and signed by Perry that closed off public access to records showing who has concealed handgun licenses.
