Can't download today.com video

[hub2git]

I'm trying to download the 9:38 video on http://www.today.com/video/brian-williams-talks-to-matt-lauer-in-first-interview-since-suspension-468065347576. So I did this in my terminal

youtube-dl "http://www.today.com/video/brian-williams-talks-to-matt-lauer-in-first-interview-since-suspension-468065347576"

Here's the printout:
