Speaking to hundreds of mayors from around the country, Vice President Joe Biden made a case for President Barack Obama’s sweeping executive orders and proposed legislation to curb gun violence, but he did not lay the blame exclusively on weapons.

“This isn’t just about guns,” Biden said on Thursday at the U.S. Conference of Mayors in Washington, D.C. “It’s about the coarsing of our culture.

“Yes, that’s what I said, the coarsening of our culture, whether it’s with video games or movies or behavior,” Biden said.
