Washington ? A key House committee Thursday approved most of the funding requested by President Bush for the occupation and reconstruction of Iraq, after heavy White House lobbying quelled a rebellion among Republicans who were demanding that Iraq eventually repay part of the aid for helping rebuild the war-scarred nation.

Bowing to personal pleas from Bush and his top foreign policy lieutenants, dissident Republicans on the House Appropriations Committee agreed to drop planned amendments to the $87 billion bill that would have made some of the reconstruction aid a loan rather than a grant.

The committee approved the bill, 47-14, after trimming almost $2 billion from the $20 billion Bush had requested for reconstruction. The bill omitted money for several specific projects — such as buying garbage trucks and establishing a ZIP code system — that members of both parties regarded as unnecessary or hard to justify at a time when domestic infrastructure projects are being squeezed.

The legislation, which goes to the full House next week, also includes $66 billion for military operations in Iraq and Afghanistan.

In another departure from the administration’s request, the committee increased by 50 percent — from $800 million to $1.2 billion — the funding being sought for reconstruction aid to Afghanistan.

The additional money would be used to pay for roads, electricity, economic development and elections.
