KEY POINTS:
United States President George W. Bush says the Israeli-Palestinian peace process does not depend on Israeli Prime Minister Ehud Olmert.
In interviews with Israeli media, Bush has named Israel's foreign and defence ministers as possible replacements for Olmert.
The comments came amid speculation that Olmert will have to step down over an ongoing police investigation.
According to the allegations, Olmert accepted large sums of cash from an American donor.
Olmert has said he will resign if indicted.
Bush will visit Israel this week.
