John Thune, R-S.D., said in a statement. “When such breaches occur, urgent action is necessary to protect sensitive personal information. This hearing will give the public the opportunity to hear from those in charge.” Yahoo and Equifax were the victims of two of the largest data breaches in history.

Verizon said earlier this month that a previously disclosed Yahoo hack in 2013 affected every single Yahoo customer — roughly 3 billion accounts.
