"Jack and I agree that recent events have made it difficult for him, both personally and professionally, to stay in a job and industry that we know are important to him," Michael A. Carpenter, the chief executive for the company, a subsidiary of Citigroup, wrote in a letter to employees.
Grubman, whose research reports once sent stock soaring, is now under fire for his unwavering recommendations for companies that were also paying millions of dollars to his firm for investment banking services.

Grubman has been targeted by at least 40 consumer complaints and lawsuits, many of them related to the WorldCom collapse.
Testifying before the House Financial Services Committee last month, said he had no idea that WorldCom executives hid billions in expenses from investors.
