Top official of the U. S. Chamber of Commerce said on Monday that the organization will not support any effort to repeal healthcare reform legislation.

They will introduce legislation to repeal the landmark measure, which the House passed Sunday and President Barack Obama is expected to sign on Tuesday, several members of Congress have said.

Chamber of Commerce President Thomas Donohue, in an interview with Wall Street Journal editors and reporters, was critical of the legislation but said the organization would not commit chamber resources to a repeal effort.

The legislation is "very, very expensive" and will disrupt the U. S. healthcare system. The chamber -- which represents an estimated 3 million U. S. businesses -- was a significant player in the campaign against healthcare reform passage, Donohue said.

Donohue told the Journal, "If people want to try and repeal, let them. We're not going to spend any capital on that."

The chamber will try to influence the process in which regulations are developed for enforcement of the new law, he further said.

Donohue also said, "There's never been a bill this size ever written on anything that doesn't go back for adjustments and refinements." (With Inputs from Agencies)
