The Media Research Center (MRC) found in 2018 that when it comes to censoring conservatives on social media, Twitter was the clear leader. The same year, former CEO Jack Dorsey claimed in front of Congress that it does not make decisions based on “political ideology,” and strives for impartial enforcement. Dorsey was CEO 2015-2021. Under his leadership, the platform morphed from a free speech free-for-all to a haven for the left and a censor of the right.
Parag Agrawal took over as company CEO in November 2021. Prior to his promotion, Agrawal said Twitter's role was "not to be bound by the First Amendment."
Twitter’s culture and workforce is so liberal that conservative staff members “don’t feel safe to express their opinions,” Dorsey said in an August 2018 interview. This liberalism also shows up in whom it suspends or bans, members of its Trust and Safety Council, whom and how it fact-checks, and in how it defines hateful or violent content. Its fact-checking team is led by Yoel Roth, who has called the Trump administration “ACTUAL NAZIS IN THE WHITE HOUSE.” Its Trust and Safety Council is also chock-full of liberal groups including GLAAD and the Anti-Defamation League.
