WASHINGTON – Sen. Mike Lee (R-UT) issued the following statement Thursday after reviewing the responses from letters to the CEOs of Alphabet, Facebook, Squarespace, and Twitter asking each company to justify anti-conservative bias in their content moderation process.

“The responses received from the tech companies about bias against conservatives at their firms were completely unpersuasive,” Sen. Lee said. “I continue to be concerned about the ideological discrimination going on at these firms and I believe further oversight will be necessary in order to obtain the facts and answers that the American people deserve.”
