A proposed ban on judges belonging to the Federalist Society and the American Constitution Society is drawing increased attention from Capitol Hill as a Judicial Conference committee is set to weigh next steps for the draft advisory opinion.

Several lawmakers have sent letters to formally weigh in on the proposed opinion, first made public in January. On Monday, Rep. Jim Jordan, recently named the top Republican on the House Judiciary Committee, sent a letter to the Judicial Conference requesting details on its Committee on Codes of Conduct's formulation and consideration of the draft advisory opinion.

In the letter to Sheryl Walter, general counsel for the Administrative Office of the U.S. Courts, Jordan echoed the criticisms of other conservatives on the proposed ban on Federalist Society memberships for federal judges, noting the group does not file amicus briefs in ongoing litigation like the American Bar Association does. The draft rule distinguishes the other groups from the ABA and does not ban judges belonging to that association.
