Tahnoun bin Zayed Al Nahyan (national security advisor)

Sheikh Tahnoun was named in the lobbying scandal of Tom Barrack, advisor and fundraiser of former US President Donald Trump. As per the indictment against Barrack, he was charged with lobbying the former administration on behalf of the UAE government and royals without registering himself as a foreign agent of the Gulf nation. The indictment cites three Emirati officials as number 1, 2 and 3, which as per people familiar with the matter are, Sheikh Tahnoun as the Emirati Official 2 and his brother and Abu Dhabi Crown Prince Sheikh Mohammed bin Zayed Al Nahyan as Emirati Official 1. The director of the Emirati intelligence service on the other hand was named as Official 3 in the indictment. In 2022, Barrack was found not guilty on all charges.

In December 2022, Qatar denied its involvement in the alleged bribery case. The Qatari government accused the UAE of orchestrating the scandal. European Union correspondent Jack Parrock confirmed Qatari government officials believe that the scandal against Qatar has been planned by the UAE. An Italian news site, Dagospia alleged that it was the UAE national adviser Tahnoun bin Zayed Al Nahyan who executed the scandal against Qatar and provided tips to Belgium, which opened the investigation.

Sheik Tahnoun runs the Royal Group, which is a UAE conglomerate. In 2021, the company was involved in controversial deals to re-sell Russia's Sputnik vaccine to poor countries at substantial mark-ups.

In October 2021, the International Consortium of Investigative Journalists (ICIJ) released a report based on over 11.9 million documents, which also mentioned the name of Tahnoun bin Zayed, alongside Mohammed bin Rashid Al Maktoum and Hazza bin Zayed Al Nahyan.

Sheikh Tahnoun received Yossi Cohen, the Head of Israeli Intelligence Agency, Mossad on 18 August 2020, after the success of the UAE-Israel peace accord.

On 16 August 2020, The Wall Street Journal reported about the administration led by US President Donald Trump of imposing several sanctions against the regime of Syrian President Bashar al-Assad, targeting financial-support networks aiding the President from outside the country, to coerce Damascus into peace talks. According to financial records reviewed by The Wall Street Journal, Sheikh Tahnoun deposited about $200,000 into the bank accounts held by the niece of Syrian President Assad, Aniseh Shawkat, over a period of several years as her sponsor. The UK authorities seized several of these bank accounts in 2019, claiming that hundreds of thousands of dollars deposited in the accounts of Ms Aniseh helped circumvent European Union’s sanctions against the Syrian regime funds. Sheikh Tahnoun, Aniseh Shawkat and her attorney Zubair Ahmad did not respond when reached out for comment.

The Central Intelligence Agency of the United States was condemned for spying to all nations in the Arab world and Middle East region, except the UAE, despite the Gulf nation having hired former CIA officials for its Project Raven to spy on political targets, including several American in 2014.

Sheikh Tahnoun is an avid practitioner and patron of martial arts, especially Brazilian jiu-jitsu. In 1998, he created the ADCC Submission Fighting World Championship alongside his BJJ instructor Nelson Monteiro.
