President George W. Bush is expected to reject Tuesday a $5.1 billion anti-terror package approved by Congress last month, which will cost Israel $200 million extra aid authorized as part of the package.

The package was aimed at boosting airport security and funding other programs, officials said.

The counter-terrorism budget bill brings together 84 different projects and can only be approved in full. Bush, who does not object to the $200 million in aid put aside for Israel in the bill, or the $144 million set aside in humanitarian aid for the Palestinians, supports only some of the projects.

Bush plans to announce the decision at an economic forum he is staging at Baylor University in Waco, Texas, on Tuesday as part of an effort to shore up support in his administration's economic stewardship as stock markets have tumbled and federal budget deficits have ballooned.

Following its approval by the House of Representatives and the Senate, the package was sent to Bush for his signature; however, the president believes that the additional sum approved by Congress is higher than necessary, according to Treasury Department calculations. By law, if the president fails to ratify the budget within 30 days, it is annulled.
