Millions of poor American children are at risk of losing their health insurance unless a compromise is reached between President Bush and Congress by the end of the month.

Democrats want to add billions to the State Children's Health Insurance Program; President Bush says that will result in a veto.

President Bush drew new battle lines with Congress over the so-called S-Chip, the state Children's Health Insurance Program. Democrats want to increase spending by $35 billion; President Bush says he'll veto that.

The S-Chip provides health insurance for millions of children whose families don't qualify for Medicaid, but can't afford private insurance.

"Congress made the decision to expand the eligibility of this program for families making up to $8,000...that's not the intent of the program...the intent is to provide poor children health insurance,” said Bush.

Democrats deny that eligibility rules are changed in the bill.

"Just because the president has a bully pulpit doesn't mean he is accurate or right,” says Sen. Debbie Stabenow from Michigan.

The White House has proposed new rules making it harder for states to insure all but the lowest-income children. Fourty-four senators, including six republicans have asked Mr. Bush to reconsider.

Democrats plan to fund the increase with a tobacco tax.

"The moment of truth is now...the President is saying I forbid health insurance for ten million American children...you know Latin, that's what the word veto means,” House Speaker Nancy Pelosi.

Time is running out, the program expires September 30th unless a compromise is reached.

"If they fail to do so, more than a million children could lose health coverage,” says Bush.

President Bush says short of a compromise, Congress should send him a temporary extension of the program.

But Democrats say this latest bill is already a compromise, they originally proposed a $50 billion increase for the program.
