"Although several possible approaches were actively discussed, Congress ultimately did not pass any legislation in 2015. But these approaches remain open for 2016....

The Roe-Larson bill ... would make largely parallel changes to ERISA. Both bills would prohibit the DOL from amending the current fiduciary investment advice definition unless Congress specifically approves such a DOL rule within a specified time period."
