President Donald Trump has summoned several representatives of social media participants to a summit at the White House Thursday afternoon.

White House spokesman Judd Deere said last month that the meeting “will bring together digital leaders for a solid conversation about the opportunities and challenges of today’s online environment.”

The president sent a tweet Thursday morning about the meeting: 

“A big subject today at the White House Social Media Summit will be the tremendous dishonesty, bias, discrimination and suppression practiced by certain companies. We will not let them get away with it much longer. The Fake News Media will also be there, but for a limited period.”

He added in another tweet: “The Fake News is not as important, or as powerful, as Social Media. They have lost tremendous credibility since that day in November, 2016, that I came down the escalator with the person who was to become your future First Lady….”

President Trump has criticized Facebook, Twitter, and Google on several occasions for having a bias in favor of Democrats and leftists. In a television interview with Fox News last month, the president told journalist Tucker Carlson that Twitter made it “very difficult for people to follow me on Twitter (…) and they make it much harder for me to spread a message.”

Some of the participants announced on social networks that they will be at the summit, among them radio broadcaster Bill Mitchell and African American activist and influencer Ali Alexander.

According to the media, there will also be conservative foundations such as the Heritage Foundation, the Claremont Institute, and the Veritas Group.

It is still unclear whether Twitter and Facebook will be present. They are platforms that have received numerous complaints about censoring conservative figures, including the influencers Diamond and Silk.

The summit is scheduled to begin at 3:45 p.m. EDT. Afterward, President Trump will hold a press conference.
