In other news from Washington, President Bush is expected to issue the fourth veto of his presidency today on a bill expanding health insurance to millions of low-income children. Congress sent the bill to the White House on Tuesday. It calls for a $35 billion spending increase to the State Children’s Health Insurance Program, known as S-CHIP. The increase would be financed through a tax increase on cigarettes. Bush has promised a veto because he says the measure would encourage government-backed healthcare.
