Here’s a nice opinion piece. By the Christian Science Monitor, no less.
Dianne Feinstein has a history of getting policy around cryptography and security utterly and disastrously wrong. She backed the regressive ITAR regulations banning export of strong crypto (which had the actual — and intentional — effect of reducing security of software in the US). She backed the Clipper Chip program in the 1990s, claiming a need for “balance” by mandating that US citizens use only government-approved cryptography (the Clipper protocol contained serious flaws which were exposed a few months after the specification was published). She backs the FISA secret courts. She has refused to investigate wrongdoings by the NSA and other intelligence communities, or to investigate the clear and blatant lying by government officials about surveillance programs to congress (last I checked perjury was still a pretty serious offense; Senator Feinstein is apparently just fine with it).
She has so clearly demonstrated her incompetence and misservice to her constituents and to the US at large that we should be done with her. Dianne Feinstein is a danger to our collective security, and she should either step down, or be removed from the Senate Intelligence Committee.
