In Memoriam: Mark Klein, AT&T Whistleblower Who Revealed NSA Mass Spying


Mark stood up and told the truth at great personal risk to himself and his family. AT&T threatened to sue him, although it wisely decided not to do so. While we were able to use his evidence to make some change, both EFF and Mark were ultimately let down by Congress and the Courts, which have refused to take the steps necessary to end the mass spying even after Edward Snowden provided even more evidence of it in 2013.
