Lieberman’s office has clarified to me how the law would work: It would empower the State Department to conclude — on its own — that Americans are conspiring with terror groups and should be stripped of their citizenship.
Lieberman’s law would amend an earlier statute that details other things that can cost you citizenship: Serving in the army of a foreign state, pledging allegiance to a foreign state, and so on. In those cases the State Department decides whether your disloyalty merits loss of citizen status. Lieberman’s law would add involvement with a foreign terror organization — as opposed to a foreign state — to this list…
You would still have the right to contest this in court. And if you did, the burden of proof would be on State — not on you — to persuade the court that your involvement with a terror organization is sufficient to justify taking away your citizen status.
