Naturally, it’s from The Donald.
Wow, CNN had to retract big story on "Russia," with 3 employees forced to resign. What about all the other phony stories they do? FAKE NEWS!

So far as I can tell, CNN withdrew the story because it was insufficiently sourced; there has not been a finding that it was in error.
