Facebook whistleblower to take her story before the US Senate

Frances Haugen, who came forward accusing the company of putting profit over safety, will testify in Washington on Tuesday

A former Facebook employee who has accused the company of putting profit over safety will take her damning accusations to Washington on Tuesday when she testifies to US senators.

Frances Haugen, 37, came forward on Sunday as the whistleblower behind a series of damaging reports in the Wall Street Journal that have heaped further political pressure on the tech giant. Haugen told the news program 60 Minutes that Facebook's priority was making money over doing what was good for the public.
