text:  Todd Frankel was the lead reporter on the main story of a Washington Post series on the history of the AR-15. The series won a Pulitzer Prize for National Reporting this year, and the Post has just reposted that AR-15 series. After we take a short break, we'll take a deeper dive into the history of the AR-15 and its current place in gun culture, and listen back to the interview we recorded last year when the series was published. This is Fresh Air.
