Republican lawmakers have been using congressional hearings as an opportunity to grill the CEOs of tech companies whose online platforms, they allege, discriminate against conservative content.
Republicans typically use their time during the hearings to demand to know why tech platforms "censor" posts from President Donald Trump, intentionally silence voices on the right, and stifle free speech.
These talking points have proven to be effective messaging for senators seeking election, as well as for expanding the Republican Party's reach online.
Twitter and Facebook have been fielding accusations over anti-conservative bias for years now, after Republicans' criticism of the tech companies increased soon after Trump's election in 2016.
And as the political climate grows more polarized, more platforms will emerge that run on lighter enforcement of online rules.
