The Employment Non-Discrimination Act is set to be introduced in both chambers of Congress on Thursday, according to multiple sources, but without major changes that were previously under consideration. The bill will be reintroduced in the House by Rep. Jared Polis (D-Colo.), the most senior openly gay member of the chamber, who’s taking over the legislation now that former Rep. Barney Frank has retired. In the Senate, the legislation will be reintroduced by Sen. Jeff Merkley (D-Ore.). The lawmakers’ offices confirmed they would introduce ENDA concurrently on Thursday. The Senate version of the bill will have five original sponsors: Merkley and lesbian Sen. Tammy Baldwin (D-Wis.) will be two Democrats, Sens. Mark Kirk (R-Ill.) and Susan Collins (R-Maine) will be two Republicans and Senate Health, Education, Labor and Pensions Committee Chair Tom Harkin (D-Iowa) will round out the quintet.
