The U.S. Chamber of Commerce is “already working” with Trump administration transition officials to “undo” the U.S. Labor Department’s fiduciary rule, Thomas Donohue, the president and chief executive of the business group, said Monday.

In a blog post Monday, Donohue said the Chamber is “urging immediate action to undo” the fiduciary rule, because “if enacted, it would choke economic growth, increase frivolous litigation against financial advisers and make saving for retirement more difficult for hardworking Americans.”
