Labor Department's Wells Fargo complaint site has vanished and Elizabeth Warren wants to know why

Wells Fargo's fake account scandal -- the bank fired 5,300 workers for creating as many as 2 million fake accounts -- has revealed a toxic sales culture and allegations it mistreated workers. The Labor Department launched the website last September as a way for Wells Fargo workers to flag potential violations and learn about their rights.

"Taking down this website enables Wells Fargo to escape full responsibility for its fraudulent actions and the Department to shirk its outstanding obligations to American workers," Warren wrote.
