Former President Obama argued in a new interview that gun ownership shouldn’t be a partisan or ideological issue, amid renewed discussions of gun safety legislation in the wake of several recent mass shootings. “I think somehow — and there are a lot of historical reasons for this — gun ownership in this country became an ideological and a partisan issue in ways that it shouldn’t be,” Obama said in an interview with “CBS Mornings” co-host Nate Burleson set to air next Tuesday.
