The Freedom 7 are political activists and journalists (Noam Chomsky being probably the most famous of them) who have filed a lawsuit questioning the Consitutionality of the NDAA. Some of them have been harassed at border crossings, had their data confiscated for weeks, had their phones tapped, etc. These folks are afraid that the NDAA would redefine their activities, which are protected by the First Amendment, as nebulously defined "support" of "associated forces" for terrorism. For example, a journalist who talks to an Al-Qaeda person for a story, or an activist with Occupy, or someone who raises money for Bradley Manning's legal defense fund. The government lawyers have so far refused to define the boundaries of the NDAA and who it DOESN'T apply to.
At least one of them has an ACLU lawyer (David House, the Manning supporter). You could donate there and ask that it go to his defense. Or if you're broke, just pass on this story.
