Author Matthew Cole, in his book Princes and Thieves, accused Jared Kushner of having access to over $2 billion in secret foreign bank accounts linked to Middle Eastern leaders, which were allegedly used for influence operations and to finance unofficial diplomatic activities during his time as a senior adviser in the Trump administration. Cole's book claims that these funds were part of a broader scheme involving the UAE and Saudi Arabia to manipulate US foreign policy

Vanity Fair published an excerpt from the book, reporting that Dutch military intelligence hacked into Kushner's phone in 2018 and discovered hundreds of millions of dollars in bank transfers connected to Emirati monarch Mohamed bin Zayed (MBZ).

Cole says that MBZ wants to reshape the Middle East and eastern Africa into an alliance of U.S.-backed dictatorships, where "tolerance" is enforced through high-tech surveillance and "democracy" is a synonym for terrorism.

Cole claims Kushner was personally involved in MBZ's mercenary operations. MBZ and Saudi Crown Prince Mohammad bin Salman put a collective $2 billion into Emirati and Israeli bank accounts which were managed (but not technically owned) by Kushner, according to Cole's sources. Those same sources claim that parts of this secret "slush fund" went to Libyan warlord Khalifa Haftar, American military contractor Erik Prince, and Cuban hitman Felipe

Jared Kushner denies the allegations.
