When a foreign government official invests half a billion dollars in a presidential family's crypto venture, and then shortly after gets approval for something they've been seeking from that same administration, people tend to notice. Senator Elizabeth Warren certainly did.

The $500 Million Investment

Sheikh Tahnoon bin Zayed Al Nahyan, who serves as the UAE's national security adviser and is a senior member of the royal family, backed a $500 million investment in World Liberty Financial, according to a Wall Street Journal report published Saturday. The report cited company documents and sources familiar with the transaction.

The investment came through Aryam Investment, a firm backed by Sheikh Tahnoon, which acquired a 49% stake in the company. That makes it World Liberty Financial's largest known shareholder by a considerable margin.

World Liberty Financial is the company behind USD1, a stablecoin pegged to the U.S. dollar and backed by short-term U.S. Treasurys, dollar deposits and cash equivalents. President Donald Trump and special envoy Steve Witkoff are listed as co-founders emeritus, while day-to-day operations are handled by members of the Trump and Witkoff families.

According to the Journal's report, about $187 million from the deal went to Trump family entities, with another $31 million flowing to Witkoff family entities.

Timing Raises Questions

Here's where the timeline gets interesting. Eric Trump signed the agreement just days before his father's second inauguration, the report said. At that exact moment, the UAE was actively seeking access to advanced U.S. artificial intelligence chips that had previously been blocked over concerns they might end up diverted to China.

Fast forward a few months, and the U.S. approved the sale of hundreds of thousands of Nvidia Corp (NVDA) AI chips to the UAE. About one-fifth of those chips were earmarked for G42, an AI firm controlled by none other than Sheikh Tahnoon.

Warren Demands Answers

Warren, who serves as the top Democrat on the Senate Banking Committee, didn't mince words. She called the situation "corruption, plain and simple" in a post on X.

The Massachusetts senator demanded congressional testimony from Witkoff, White House AI and crypto czar David Sacks, and Commerce Secretary Howard Lutnick. She said they need to explain whether U.S. national security was compromised for private financial gain.

"Congress needs to grow a spine and put a stop to Trump's crypto corruption," Warren wrote.

White House Pushes Back

White House spokesperson Anna Kelly told the Wall Street Journal there were "no conflicts of interest," adding that Witkoff is working to advance Trump's foreign policy goals.

Neither the White House nor World Liberty Financial immediately responded to requests for additional comments.
