Republicans recently have accused social media platforms of discriminating against conservatives.

Last month, GOP members of the House Judiciary Committee pushed for a hearing with pro-Trump video personalities “Diamond and Silk” over their claims they were censored by Facebook.

Facebook confirmed earlier this month that it was bringing in two outside advisers to help run an audit on the platform’s community impact to prevent alleged bias against conservatives.
