Here is more from the Washington Post:
U.S. intelligence officials have compiled a classified report detailing extensive efforts to manipulate the American political system by the United Arab Emirates, an influential, oil-rich nation in the Persian Gulf long considered a close and trusted partner.
The activities covered in the report, described to The Washington Post by three people who have read it, include illegal and legal attempts to steer U.S. foreign policy in ways favorable to the Arab autocracy. It reveals the UAE’s bid, spanning multiple U.S. administrations, to exploit the vulnerabilities in American governance, including its reliance on campaign contributions, susceptibility to powerful lobbying firms and lax enforcement of disclosure laws intended to guard against interference by foreign governments, these people said.
The UAE has spent more than $154 million on lobbyists since 2016, according to Justice Department records. It has spent hundreds of millions of dollars more on donations to American universities and think tanks, many that produce policy papers with findings favorable to UAE interests.
The article notes that boosters of the UAE within US think tanks often call it "Little Sparta" for its "military prowess while sidestepping its human rights record and ironclad kinship to Saudi Arabia."
Here is a Quincy Institute for Responsible Statecraft report entitled "Gulf funded think tank turns pro-Saudi, UAE messaging up to 11."
