The NAACP is reportedly calling for a meeting with Facebook CEO Mark Zuckerberg, citing concerns of hate speech on the social media platform.

The move by the civil rights organization comes after former Facebook employee and whistleblower Frances Haugen told a Senate subcommittee Tuesday that a study showed the company had only taken action on 3 to 5 percent of hate speech on the platform.

“Vaccine hesitation, political violence and white supremacy are rampant,” NAACP President and CEO Derrick Johnson said in a statement, according to Bloomberg News, referring to the statistic. “Profiting on hate and disinformation is sickening and evil.”
