Facebook has cut ties with a conservative public relations group called Definers hours after a Wednesday New York Times story revealed that the group had circulated a document linking some of Facebook's left-wing critics to liberal billionaire George Soros.

According to the Times, Facebook initially hired Definers to help the tech company monitor media coverage of the company. But in October 2017, Definers started to play an active role in defending Facebook.
