Facebook CEO Mark Zuckerberg and other employees on Wednesday reassured representatives of conservative news outlets that the company will strive to make sure that the giant social media company doesn’t bury right-leaning news stories, and that it realizes the importance of staying neutral.

Zuckerberg invited more than a dozen conservative writers and leaders of right-leaning media groups for a meeting in California on Wednesday. The meeting was called after Gizmodo reported that former Facebook employees would make sure that news favored by conservatives was downplayed on the “trending topics” section of people’s Facebook newsfeeds.
