Since you provide no links, one must assume that you are motivated by a vague awareness of controversies tied to the Clinton Foundation. However, these controversies do not involve Haiti or missing money, and for balance I suggest readers look at last fall´s and recent comparisons of the controversies surrounding Clinton and Trump associated charitable activities
Actually, the theories connecting missing Haiti donation money and the Clintons don't so much refer to the Clinton Foundation, but to Hillary's tenure at the US Department of State during which the Haiti earthquake occurred.
I won't claim to know much about the situation, but major news organizations have reported on what appears to be similar mismanagement of the ~13 billion in funds donated to Haiti [1]. And Bill Clinton found himself co-chairing the commission that handled these funds.
The conspiracy theories around the Clintons and Haiti are persistent from a number of angles. Emails from the Podesta leak added fuel to the fire, among them this one featuring a close Clinton associate mentioning "Tony Rodham ... hustling gold mining deals in Haiti."
