President George W. Bush has phoned embattled Israeli Prime Minister Ehud Olmert to extend his warm wishes.

A White House spokesman said Bush talked with the Israeli leader Wednesday just before Olmert announced in Israel that he will resign in September. Spokesman Gordon Johndroe said Bush intends to work closely with Olmert until that time, and wishes him well.

Johndroe says Bush has appreciated Olmert's friendship, leadership and work for peace.

Olmert is resigning amid police investigations of corruption allegations against him. The probes have raised doubts about Olmert's ability to strike a peace deal with Palestinians this year, as Bush wants, and his resignations increases those doubts.
