WaPo:

Google, Facebook and Twitter executives came to Capitol Hill to testify about election security. Instead they faced a grilling about whether their platforms are biased against conservatives.

A string of Republicans on the House Oversight and Reform Committee skipped questions about how the companies were tackling disinformation campaigns or preventing Russians from purchasing political ads on their platforms in the run-up to the 2020 election. They were more interested in whether Facebook and Twitter were “shadow-banning” — quietly blocking or restricting — conservatives’ accounts on their platform….

The hearing highlights how Republicans have made it their default playbook to hammer the tech companies on this single issue over all others — even when faced with pressing national security concerns about foreign influence campaigns ahead of the 2020 elections. But it also underscores how, even in a divided Washington, both sides are threatening to crack down on Big Tech — though they have very different motivations for doing so.
