As Ohio Sen. Rob Portman traveled through the state during this week's congressional recess, he got plenty of heat for his recent vote against a bipartisan bill that would have expanded background checks to more gun sales.
Groups in favor of the legislation protested some of his appearances and an Ohio woman whose son was killed in last year's mass shooting at a Colorado movie theater tried to meet with Portman to express her frustration with his vote.
Jerri Jackson of Springfield told the Cleveland Plain Dealer and the Dayton Daily News that she thinks a background check might have kept her son's killer from buying a gun after police expressed concerns over his mental health.
Portman says he didn't think the legislation would help prevent mass shootings.
