The United States will send an official delegation to observe the Palestinian elections due on Sunday, State Department deputy spokesman Adam Ereli said on Wednesday.

"The delegation will be led by Senator John Sununu of New Hampshire and Senator Joseph Biden of Delaware, both of the SenateForeign Relations Committee," Ereli said at a news briefing.

"It will also include four congressional staff members, prominent Palestinian-Americans and our consul general in Jerusalem, Mr. David Pearce, will join the delegation when it arrives. That delegation will meet with senior Israeli and Palestinian officials. It will visit polling sites. And prior to departing, it will make an assessment of the election process," Ereli said.

Ereli said that the United States is working with both Israelisand Palestinians to support successful administration of the elections.

US President George W. Bush has stressed that the Palestinian leadership achieves democracy to realize his vision of two states,an Israeli and a Palestinian, living side by side in peace and security.
