Report: N.Y. Investor Called to Testify in Israeli Scandal

Raviv shares the same Woodmere, N.Y., address as Talansky and his wife, according to the tax return. No one answered the phone at Talansky's residence and that of several of his relatives.

Back in 2000, opposition members of the Jerusalem City Council accused Olmert of using the foundation as a fundraising tool for his political career, telling the Jerusalem Post that they "fear the mayor has been using it ... to raise funds for his own political needs."

At the time, Olmert told the paper that the foundation had raised $4.5 million, deposited in "city banks" and that it was being used to fund 80 projects. Much of the foundation's money was reportedly raised by evangelical Christian groups in the United States.

One of the group's donors has been Rabbi Yechiel Eckstein, the president of the Chicago-based International Fellowship of Christians and Jews.

The only number listed on the 2006 tax return for the foundation is a New York-based accounting firm, where a staffer told ABCNews.com that Talansky is their only official contact with the organization.

Talansky has also been an active fundraiser for the American Committee for Shaare Zedek Hospital in Jerusalem.

Talansky made headlines last year when he and other investors sued an Israeli satellite company called ImageStat, alleging the firm failed to provide access to the satellite's images to Venezuela, Angola, Russia and Taiwan, due to diplomatic concerns.

A lawyer for the plaintiffs declined to comment except to say that the case remains pending.

Talansky has been a bipartisan campaign contributor in American politics, raising $1,000 for President Bush in 2003, Rudy Giuliani's 2000 Senate campaign and Bill Clinton's re-election in 1996.
