Occasionally you'll here something true, like who won last night's basketball game, but in general most of what is said on CNN, MSNBC, and their ilk, or by someone with a "D" after their name is just fiction.
The only reason they tell the truth about basketball scores is they haven’t figured out a way to lie about them. I’m sure it irks them to have to tell the truth about anything, but in sports reporting they are stuck with it.
Notice they have figured out a way to lie about the weather.
