This is a mailer from the National Association for Gun Rights. Inside is a fundraising letter sent by Sen. Rand Paul:
The quote on the outside of the mailer comes from an Obama speech after the Newtown shooting. Obama's quote was not about banning guns, it was about engaging citizens.
This is the full quote:
"In the coming weeks, I'll use whatever power this office holds to engage my fellow citizens — from law enforcement, to mental health professionals, to parents and educators — in an effort aimed at preventing more tragedies like this, because what choice do we have? We can't accept events like this as routine."
