Republican Senator Jim DeMint of South Carolina requested  documents from the National Labor Relations Board (NLRB), Monday, in connection with the ongoing lawsuit over Boeing moving a production plant to Charleston, S.C.

The request, made through the Freedom of Information Act (FOIA), seeks documents pertaining to the NLRB's decision to go after Boeing's decision to relocate to a right-to-work state. Specifically, it includes communications between NLRB and union officials at the International Association of Machinists (IAM) and officials in Congress and the Obama Administration.

The FOIA letter was sent to Lafe Solomon, Acting General Counsel at the NLRB, and Jacqueline Young, General Counsel and FOIA Officer at the NLRB.

"The public facts surrounding the complaint raise serious questions about the interpretation of the National Labor Relations Act upon which it is based, to say nothing of the troubling appearance of partisan, special interest politics at its heart," read the letter.
