O ok. In that case, the track should be easy to find.
I suspect this could actually be stock music though. If that's the case, the guy's name is Tim Helisek, though the stock music he composed was only used in episodes from 2011-2012.
The director of the episode you recorded it from might be Kate D'Arcy-Coleman, though she might not know about the music but you could still contact her. Give it a shot at least, I would say.

Or you can look at this https://en.wikipedia.org/wiki/CBS_News_Sunday_Morning That's got everything, I think.
