The congresswoman also said that Facebook executives should testify about Libra as part of that oversight.

We’ve asked Facebook for comment. As part of the announcement, though, it launched a Libra Association whose aim is to oversee the currency outside of Facebook’s control. Calibra, the digital wallet for the new monetary format, is supposed to share only limited data with Facebook and have “strong protections” such as automated fraud checks.

Those measures might not satisfy politicians. Numerous federal and state regulators are investigating Facebook’s behavior in recent years, and there’s no question that the internet giant has been awash in privacy debacles even after the Cambridge Analytica scandal had seemingly wound down. Waters and others just don’t have much of a historical basis to trust what Facebook says, even though it appears to be learning its lessons.
