The Labor Department has told Congress input by Securities and Exchange Commission staff has resulted in “numerous changes” in DOL’s proposed rule for retirement fund advisors.

The Department added the SEC will continue to have its voice heard on the proposal while it is under review by the Obama Administration’s Office of Management and Budget.

The comments came in a March 16 letter to House Education and Workforce Committee Chairman John Kline released by the Department of Labor on Tuesday.

In the letter, Acting Assistant Labor Secretary for Congressional Affairs Adri Jayaratne told Kline, “I am sure you would agree that all savers, regardless of their income level, deserve access to advice that is in their best interest.”

Jayaratne added the rule aims to remove outdated regulatory loopholes that make it hard for retirement savers to count on the advice they receive.

On Tuesday, Labor Secretary Thomas Perez told another House committee that SEC Chair Mary Jo White is the only SEC Commissioner he has consulted with on the rule.

“Which I think is appropriate … the Chair is the Chair,” the Labor Secretary said.

In February, Republican SEC Commissioner Daniel Gallagher criticized the Labor Department for not working closely with him on the rule which he and others have feared could conflict with fiduciary standards for advisors and broker-dealers that the SEC is developing itself.

Perez said he has participated in nine conversations with White on his department’s rule, which has been sent to the Obama Administration’s Office of Management and Budget for review prior to public release.

The letter to Rep. Kline gives the dates of four meetings and four phone calls Perez had with White on the fiduciary issue between November 22, 2013, and January 8 of this year.

In defending the guidelines, the Labor Secretary said employers have told him they want their workers to have as much money as possible when they retire.
