Sheldon Adelson, a casino magnate with a net worth of $21bn and the world's sixteenth richest man has thrown chunks of his vast fortune in US Republican presidential candidate Newt Gingrich's way.
The $10mn Adelson has contributed to groups in support of Gingrich is an example of the kinds of unlimited investment wealthy donors can contribute to US political campaigns following a controversial court ruling.
Asked why he thinks the highly pro-Israel Adelson has been in support of his potential presidency, Gingrich replied plainly "he knows I'm very pro-Israel".
But there is also fear that without Adelson's fortunes, pro-Gingrich groups and even the campaign itself may be in financial jeopardy.
