Obama “supported the Senate bill, and that — that provision was in that bill for what it does in terms of changing the direction of health care costs,— Gibbs said.Union officials object to the provision because it may hit generous health plans they’ve negotiated for some of their members.During the Monday afternoon session with top union officials at the White House, Obama is also likely to hear concerns about the lack of movement in Congress of the Employee Free Choice Act and labor objections to provisions of immigration legislation that may move this year.Asked whether Obama would be open to negotiating with labor leaders on the level of the health plan tax that has been proposed, Gibbs replied, “I certainly think the level is one of the topics that will come up.—Gibbs acknowledged that the amount of enthusiasm among labor’s foot soldiers for the president’s agenda and for Democrats in 2010 is likely to be a topic of discussion.
