"Do we still need to point out that Jesus can return only after Armageddon and to this end it is best if Israel continues to be at war?" rival politician Colette Avital wrote last month.
Yet Olmert, who once called the Christian community the most politically powerful in the world, was not the first Israeli politician to tap the evangelicals for money. He was, however, one of the most aggressive after being elected mayor in 1993.
"Olmert gets it," said Yechiel Eckstein, founder of a group that has raised nearly $500 million for Israeli and Jewish causes, mainly from Christians. Eckstein, a rabbi, set up the International Fellowship of Christians and Jews in 1983.
Olmert's bond with evangelicals is rooted in his platform as mayor of keeping Jerusalem united. Palestinians accuse him of spearheading Jewish settlement round the city, dividing Arab East Jerusalem from the West Bank, both occupied by Israel in 1967.
Olmert headed the New Jerusalem Foundation, set up in 2000 to fund charity projects in the city, and records filed with Israel's Justice Ministry show that groups like Eckstein's International Fellowship were among the largest donors.
In Israel, the New Jerusalem Foundation, which is now headed by Olmert's successor as mayor, said in a statement to Reuters that it was not under investigation and described the US branch as a "separate legal entity" that it never oversaw.
Public documents indicate financial links between the two.
MILK COW GOES SOUR
"The United States is one of the best milking cows in the world. You come to the United States and you milk," said Ranan Gissin, an aide to former prime minister Ariel Sharon.
"It's not just the money. It's the political support. We're talking about 70 million people," Gissin said of evangelicals.
Olmert was long a familiar speaker on the US fundraising lunch and dinner circuit. Public records show that, for example, he attended a series of three meetings in churches organised by a group known as the Jerusalem Prayer Team, whose founder Mike Evans's stated mission is "to protect the Jewish people...until Israel is secure and the redeemer comes to Zion".
From 2002 to 2004, church fundraisers organised by the Jerusalem Prayer Team, including the one in Dallas, raised $239,300 for the New Jerusalem Foundation. NJF records say it spent its money on parks, charity meals and other programmes.
But Olmert's relationship with many Christians has soured.
"I think he's changed over the years and power can do that," said one pastor who attended Olmert's fundraisers in the past.
"I don't think it's the same Ehud Olmert that we knew."
Evangelicals did not oppose all talks, Gissin said, but were firmly against "giving away holy real estate like Jerusalem".
A group of Christian leaders, including George Morrison from Colorado, met Olmert in April: "When he was mayor, he found a friend in evangelical Christians and evangelical Christians found someone strong on Jerusalem," Morrison said. But now many Christians were "questioning if he is on the same page".
In a declaration he read to Olmert on behalf of the group, which also included Hagee and Evans, Morrison assured the prime minister that American evangelicals could mobilise to try to stop Bush or his successor pressing Israel into giving up land.
In January, Evans made clear his view of Annapolis: "I was completely outraged when I heard that Ehud Olmert, whom I have known for 26 years, stood next to President Bush and declared that he would work to fulfill the final status solution.
"This means the division of Jerusalem," he wrote on his Web site. "I will do everything in my power to resist that."
