"Democrats in Congress have decided to pass a bill they know will be vetoed," Bush said of the measure that draws significant bipartisan support, repeating in his weekly radio address an accusation he made earlier in the week. "Members of Congress are risking health coverage for poor children purely to make a political point."

At issue is the Children's Health Insurance Program, a state-federal program that subsidizes health coverage for low-income people, mostly children, in families that earn too much to qualify for Medicaid, but not enough to afford private coverage. It expires Sept. 30.

A bipartisan group of lawmakers announced a proposal Friday that would add $35 billion over five years to the program, adding 4 million people to the 6.6 million already participating. It would be financed by raising the federal cigarette tax by 61 cents to $1 per pack.

The idea is overwhelmingly supported by Congress' majority Democrats, who scheduled it for a vote Tuesday in the House. It has substantial Republican support as well.

But Bush has promised a veto, saying the measure is too costly, unacceptably raises taxes, extends government-covered insurance to children in families who can afford private coverage, and smacks of a move toward completely federalized health care. He has asked Congress to pass a simple extension of the current program while debate continues, saying it's children who will suffer if they do not.
