2. He says he’s open to reconsidering the size of gun magazines

“I have traditionally not supported looking at magazine clip size and after this and some of the details I have learned about it, I am reconsidering that position and I’ll tell you why,” he said. “Because while it may not prevent an attack, it may save lives in an attack. … I know there are, for example, handguns that have 17. So we’ll have to get into that debate, but that is something I believe that we can reach a compromise (on) in this country, and that I’m willing to reconsider.”

Changing the rules around high-capacity magazines is a big deal because it’s not among the top proposals congressional leaders have been highlighting when discussing gun violence.

He was responding to a question about whether lawmakers should address the creation of large capacity magazines that are capable of firing 15-30 rounds of bullets or more.
