JOHN YANG:

Thanks, Judy.

Beginning next year, the Boy Scouts will allow young girls to become Cub Scouts. And then, in 2019, they will begin a program for older girls that will allow them to earn the rank of Eagle Scout.

Here to help understand what's going on, what is behind this historic change and what it might mean for the Girl Scouts, we're joined by Associated Press national writer David Crary.

David, thanks for joining us.
