Beware of "Fake News"

Be skeptical of news that comes to you through third-party channels (social media, such as Facebook and Twitter, and even web searches).

Independently verify the source (by performing a separate search) and verify the information (through trusted news sources).

Select news sources known for high-quality, investigative reporting and search these sources directly. Don't settle for web search results or social media news feeds.
