Facebook disclosed the issue in a blog post on Friday, hours before media reports that conservative-leaning Cambridge Analytica, a data company known for its work on Donald Trump’s 2016 presidential campaign, was given access to the data and may not have deleted it.

"It’s clear these platforms can’t police themselves," Democratic U.S. Senator Amy Klobuchar tweeted.
"They say ’trust us.’ Mark Zuckerberg needs to testify before Senate Judiciary," she added, referring to Facebook’s CEO and a committee she sits on.
Facebook said the root of the problem was that researchers and Cambridge Analytica lied to it and abused its policies, but critics on Saturday threw blame at Facebook as well, demanding answers on behalf of users and calling for new regulation.
