HARI SREENIVASAN, PBS NEWSHOUR WEEKEND ANCHOR:

A joint investigation by the "Associated Press" and "USA Today Network" has found in the first six months of this year, gun accidents killed at least one child in the United States every other day. The report published yesterday analyzed more than 1,000 deaths and injuries from accidental shootings involving children ages 17 and younger between January 2014 and this June.

Joining me now to talk about this is one of the reporters of that story, Ryan Foley, a member of "A.P.'s" national reporting team focused on state government coverage. He is in Iowa today.

First of all, what's the purpose of the investigation? What prompted it in the first place?
