But a Times investigation found that the claims were largely unsubstantiated. On Tuesday, Facebook released the results of a yearlong audit of its platform, which looked into the claims of conservative bias across Facebook. The audit, conducted by former Republican Senator Jon Kyl, found no evidence of bias. The findings drew criticism from Republicans like Senator Josh Hawley of Missouri, who called it a “smokescreen.” But it also prompted ire from left-leaning groups like Media Matters for America, whose president, Angelo Carusone, called the exercise part of “Facebook’s impulse to appease right-wing cries of bias.”
Facebook has said it hopes to release a test of News Tab before the end of the year.
