Trump and other top Republicans will speak at the National Rifle Association convention Friday in Louisville, where organizers are trying to unite gun-rights voters by painting Clinton as a foe of their causes who must be stopped.
Clinton will appear Saturday in Florida with the mother of Trayvon Martin and other parents who have lost children to gun violence. She's become a forceful advocate for restrictions meant to reduce the nation's 33,000 annual gun deaths.
The dual appearances highlight the opposing positions the candidates have staked out on gun rights and safety.
