Did they run out of liberal fact-checkers? Too many lawsuits on the way?

A fact-checking spinoff of the conservative website Daily Caller has partnered up with Facebook to police fake news, and mainstream media are outraged.

The social media behemoth has added Daily Caller’s CheckYourFact.com to its list of US media partners this week, sparking outrage among the mainstream (and politically rather differently aligned) media outlets, who argued that Daily Caller has published fake news, harbors “white supremacists” and was founded by Tucker Carlson of Fox News.
