To investigate who published this site, leave the Web page itself, open a new tab, and look at what the Web is telling you about the source. For example, look up the publisher on Wikipedia, to quickly check for credibility.
Original vs. Re-Reporting
Go "upstream" to find the original reporting source.
If a trusted fact-checking site (e.g., Snopes, FactCheck.org) has already verified your source, then you can rely on their work to save you tons of time!
