Business briefs from the Economist

Mark Zuckerberg was grilled in Congress about Libra, a global digital currency that Facebook hopes to launch next year but which faces mounting regulatory hurdles, causing some of its biggest backers to walk away.

The offer from the Japanese tech conglomerate increases its stake and values WeWork at around $8 billion, far below an estimate of $47 billion earlier this year. Adam Neumann, WeWork's boss, who has been blamed for the reversal of fortunes, could gain as much as $1.7 billion from the deal.
