Reuters and CNN are not FAKE news sources.
This thing about conflating legitimate news sources with 'fake' news sources is just the latest right wing tactic to delegitimize the media.
You could argue that some news sources have a bias or get things wrong from time to time.
But a 'fake' news source is one that makes up stories out of whole cloth that have no basis in reality and are solely designed as clickbait.
That is not what Reuters or CNN do.
