WASHINGTON, D.C. — US President Joe Biden blasted Meta Friday for scrapping fact-checking on Facebook and Instagram in the United States, calling the move 'really shameful' after a global network warned of real-world harm if the tech giant expands its decision to other countries.

Meta chief executive Mark Zuckerberg triggered alarm Tuesday when he announced the Palo Alto company was ditching third-party fact-checking in the United States and turning over the task of debunking falsehoods to ordinary users under a model known as 'Community Notes,' popularized by X.
