They're not official channels. I'm not sure if there are laws specifically for media but you can put out whatever content you want as a private company.

Government agencies intentionally lying is another story. Especially with Obama's Smith-Mundt act of modernization back in 2013.

I hate to say it, because I hate what the media does, but are they regulated in what they can report?

If we're talking NPR which takes public funding, I can see that. But lying to someone isn't a crime unless you're under oath or something equivalent.
