As the health care reform debate in Congress shifts to the U.S. Senate, 60 of 275 faith-based institutional investor members of the Interfaith Center on Corporate Responsibility (ICCR) are pressuring 36 major companies - including Merck, Wal-Mart, McDonald's, AT&T, IBM and General Electric -- to state publicly if the U.S. Chamber speaks for them in its campaign to kill efforts to overhaul the U.S. health care system. Significantly, all of the companies had previously agreed at the urging of shareholders to embrace health care principles that are now inconsistent with the anti-reform stance of the U.S. Chamber of Commerce on health care legislation, according to the ICCR. The letters also are signed by AFL-CIO Office of Investment; James Donovan, CPA; Progressive Asset Management Inc.; Trillium Asset Management; and Walden Asset Management. This campaign echoes corporate split with chamber over climate legislation.
