Rep. Joe Wilson (R-SC) on Friday sent a letter to House Speaker Mike Johnson (R-LA) requesting he support the South Carolina House delegation’s push for a U.S.-Europe security conference in 2027 to be hosted in Charleston, escalating a feud with Sen. Roger Wicker (R-MS) over the meeting’s location.

Wilson and Wicker chair and co-chair the Commission on Security and Cooperation in Europe, which represents the U.S. branch of the multinational Organization for Security and Cooperation in Europe. Wilson has been pushing for the OSCE conference in Charleston for more than two years, and claims he was taken aback by Wicker’s suggestion it be held elsewhere.
