The Dodd-Frank Act is under fire in Congress again.

A new bill introduced in the House Committees on Financial Services and Agriculture by a group of Republicans intent on making changes to the whistleblower rule adopted by the Securities and Exchange Commission in May seeks to make the rule more business friendly. The bill, coined as the ‘‘Whistleblower Improvement Act of 2011,” would require tipsters to report any wrongdoings to their employers first before going to the SEC as an eligibility requirement for the bounty program.
