Haystack might include MSNBC. Maddow puts out her show as a video podcast, so you can subscribe to that and watch it using an app like Pocketcasts which supports Chromecast.
Try out Haystack. It is most similar to a CNN/National news service. You can also customize it to your tastes.

Edit: This is just audio but you could also check out NPR One.
If you watch a video news service that collects reports from a variety of sources you get to see the scale of actions being taken globally. There is less chance of spin and manipulation if you can aggregate from a range of sources, for example, Haystack TV.
One of them anyway streams recent clips pulled from YouTube, so I think that's what you're looking for. Also, Haystack does this as well.
> Watchup
Is Watchup better than Haystack TV? Never heard of the watchup sauce thing.
Edit: Never mind, won't install on Android TV.
Have you checked out Haystack?

Great video news app which is a step in the right direction for Chromecast apps.
Check out Haystack TV. Not live news, but aggregates recent news segments from various sources into an easily consumable stream.
Haystack TV is pretty good.
I'm almost positive you cannot. But I use this app for news streaming in background
