A band of Republican lawmakers led by Representative Jeff Flake of Arizona and Senators Tom Coburn of Oklahoma and Jim DeMint of South Carolina has attacked earmarks, saying they waste money and corrupt the legislative process. But a larger number of lawmakers avidly seek them and boast of success in securing money for constituents. Republicans received about 40 percent of the earmarks in the spending bills for 2008.

A new tally by the White House Office of Management and Budget shows that the 2008 spending bills signed by Mr. Bush include more than 11,700 earmarks, totaling $16.9 billion. By the White House count, the number was down 1,754 from 2005, and the amount of money was down $2.1 billion, or 11 percent.

Mr. Bush recently mocked earmarks for a prison museum in Kansas and a sailing school in California.
