Among the states who have acknowledged receiving letters: Wisconsin, Oklahoma, Utah, Arkansas, Maine, Colorado, Rhode Island, Michigan, Georgia, Virginia, Louisiana, North Carolina, South Carolina, Texas, Minnesota, Iowa, Ohio and Nevada.

Off the top of my head, Texas, Utah, and Nevada are GOPers.

Oh, and that reference to 28 USC 3002? Here’s what they’re referring to:

(15) “United States” means -
(A) a Federal corporation;
(B) an agency, department, commission, board, or other entity
of the United States; or
(C) an instrumentality of the United States.

(16) “United States marshal” means a United States marshal, a
deputy marshal, or an official of the United States Marshals
Service designated under section 564.

Title 28 is Judiciary and Judicial Procedure, and Chapter 176 (Sections 3000 et seq) refers to federal debt collections.
