US prosecutors have charged eight people, including George Nader and Ahmed al-Khawaja, with conspiring and illegally diverting $ 3.5 million to support Donald Trump's 2016 presidential campaign.

US prosecutors have accused George Nader, who served as adviser to the crown prince of Abu Dhabi, and Lebanese businessman Ahmed al-Khawaja to mediate in the interest of a foreign country to members of the Trump campaign illegally.

Prosecutors said he rarely acted as a mediator in the Trump campaign for the benefit of the foreign state, which prosecutors referred to as "A", while Khawaja provided an illegal cover for such mediation.

George Nader was a key witness in Robert Mueller's investigation into Russian interference in the 2016 US presidential election.

The New York Times published in mid-August exclusive information about the money paid by the United Arab Emirates to George Nader, adviser to the Crown Prince of Abu Dhabi, to be employed in a campaign against the State of Qatar in the United States.

Nader, who is being investigated in the United States for political and sexual cases, has until recently received millions of dollars from the UAE to run campaigns in Washington against Qatar, the newspaper said in a report.

She noted that Elliot Broaidi, a businessman and co-financier of President Donald Trump's campaign, as well as Nader, received money from the UAE despite the exposure of their activities and suspicions surrounding them.

The New York Times said Nader had delivered Berwidi about $ 2.5 million in three installments since the launch of anti-Qatar media propaganda. Berwaidi paid the Hudson Institute and the Foundation for the Defense of Democracy to fund conferences to criticize Qatar.
