Facebook CEO Mark Zuckerberg promised Thursday night that he would meet with “leading conservatives” about allegations the platform suppressed right-leaning content in a section devoted to trending stories.

“In the coming weeks, I’ll also be inviting leading conservatives and people from across the political spectrum to talk with me about this and share their points of view,” he said in a post. “I want to have a direct conversation about what Facebook stands for and how we can be sure our platform stays as open as possible.”

He also said that “to serve our diverse community, we are committed to building a platform for all ideas.”

It has been a bruising four days for Facebook, since Gizmodo published allegations that the editors who work on the website’s trending topics section had avoided adding topics or news sources popular with conservatives to the list. Being featured in the section can drive web traffic to an article.

The editors, who Facebook reportedly refers to as “curators,” process topics that are generated by an algorithm meant to detect popular areas of discussion among users.

Also on Thursday, Facebook, after documents were leaked to The Guardian, released information about how the trending feature operated and published internal documents related to the product. One purported to show that several popular conservative websites, including RedState and Breitbart, were included on the list of RSS feeds that are accessed by the algorithm.

Several prominent figures on the right have attacked Facebook over the allegations. The Republican National Committee slammed the company on its website, and Senate Commerce Committee Chairman John Thune (R-S.D.) wrote to Zuckerberg asking questions about the trending feature.

Others have proved less comfortable with the prospect of elected officials pursusing a private company like Facebook.

Zuckerberg’s personal political activities have sometimes put him at odds with conservatives. He is a major supportor of immigration reform, and took a shot at presumptive Republican presidential nominee Donald Trump‘s hardline stance on the issue at a conference last month.
