"We need to constantly show that we are not adding our own bias, which I fully admit is... is more left-leaning."
What: Twitter has a "more left-leaning" bias, the company's CEO said in an interview with CNN that aired Saturday.
The acknowledgement confirmed what many conservatives have long suspected.
"We need to constantly show that we are not adding our own bias, which I fully admit is... is more left-leaning," Dorsey said.
Why: Social media networks have long been criticized for allegedly discriminating against the political right. Conservatives have lately accused Twitter of "shadow banning" conservative users.
On the other hand, many liberals have pressed Twitter to do more to regulate speech, and questioned why it has not followed other platforms in removing right-wing conspiracy theorist Alex Jones -- instead settling for a weeklong suspension.
The CEO is expected to testify next month before the Senate Intelligence Committee on the issue of Russian election interference. He may face a subpoena from the House Energy and Commerce Committee over allegations of discrimination against conservatives on the platform.
