Under the name "Coalition to Preserve American Sovereignty", John Fonte and others from the Ethics and Public Policy Center are seeking signatures for a letter pointing out just how weak State Department legal advisor Harold Koh is on U.S. sovereignty.

The letter is so far available only in JPEG form; you can see it here. It's addressed to John Kerry and Richard Lugar.

Note that page 2 references "Change for America: A Progressive Blueprint for the 44th President" from the Center for American Progress.
