From the news:
"he amendment would block the NSA from using any of its funding from this Defense Appropriations Bill to conduct such warrantless searches."
It only covers THIS appropriations bill. They'll just sneak funding into another one to make it up.
You have to pay careful attention to the language these people use.
" In addition, the amendment would prohibit the NSA from using its budget to mandate or request that private companies and organizations add backdoors to the encryption standards that are meant to keep you safe on the web."
So, money that is NOT budgeted, as in part of planned spending, as in slush fund money, is fair game.
Any time an amendment talks about what they cannot use particular money for, as opposed to simply prohibiting the action, it will be full of loopholes.
When there is an amendment that prohibits the ACTION, then we'll have something to be happy about. Nothing in this amendment prohibits the spying.
