After decades as a major Republican donor, Adelson is known as an ideological figure, motivated by his desire to influence U.S. policy to help Israel. “I’m a one-issue person. That issue is Israel,” he said last year. On that issue — Israel — Trump has delivered. The administration has slashed funding for aid to Palestinian refugees and scrapped the Iran nuclear deal. Attending the recent opening of the U.S. embassy in Jerusalem, Adelson seemed to almost weep with joy, according to an attendee.

But his reputation as an Israel advocate has obscured a through-line in his career: He has used his political access to push his financial self-interest. Not only has Trump touted Sands’ interests in Japan, but his administration also installed an executive from the casino industry in a top position in the U.S. embassy in Tokyo. Adelson’s influence reverberates through this administration. Cabinet-level officials jump when he calls. One who displeased him was replaced. He has helped a friend’s company get a research deal with the Environmental Protection Agency. And Adelson has already received a windfall from Trump’s new tax law, which particularly favored companies like Las Vegas Sands. The company estimated the benefit of the law at $1.2 billion.
