In August last year, Malaysian Prime Minister Najib Tun Razak was not happy with Saudi Arabia. He complained that the Saudis appeared to be funding an opposition candidate, Anwar Ibrahim, in upcoming elections.
What's more, the Malaysian authorities suspected two senior Saudi princes of involvement. The Saudis launched an investigation, and uncovered something very different - and more alarming.
A secret report seen by CNN concludes: "There is no evidence any Saudi official ever supported Anwar Ibrahim" and "claims of support from the Saudi royals named in the initial report [names redacted] were found to be without basis."
But the investigation found that hundreds of millions of dollars of Saudi money had been funneled to leading Islamist politicians and political activists overseas. It also found that al Qaeda and the Taliban were still able to use Saudi Arabia for fund-raising, despite numerous measures to choke off those sources of cash.
