The ranking Democratic members of the US Senate’s Foreign Relations, Banking, and Judiciary committees have written a joint letter to several Trump Administration officials asking them to address the possibility that the Trump Organization violated several laws in its dealings in Azerbaijan, according to, The New Yorker.

The concerns raised in the letter are based on an article in The New Yorker about the Trump International Hotel & Tower Baku, a project that was nearly completed but never opened.

The letter, by Senators Sherrod Brown, Dianne Feinstein, and Ben Cardin was sent to Attorney General Jeff Sessions, Treasury Secretary Steven Mnuchin, and FBI director James Comey.

The article reports that the Trump Organization worked in partnership with companies run by Elton and Anar Mammadov on the Baku luxury hotel and residence, a project overseen by Ivanka Trump. Anar is the son of Ziya Mammadov, who was, until recently, the transportation minister of Azerbaijan. Elton was, at the time of the deal, a member of Azerbaijan’s parliament. The US Foreign Corrupt Practices Act makes it a crime for American companies to provide benefit to foreign government officials in hopes of profiting from their power.

The senators also asked Mnuchin to investigate “serious questions about whether the Trump Organization may have become entangled with an IRGC [i.e. the Iranian Revolutionary Guard Corps] front organization in violation of U.S. sanctions.” As the New Yorker article spells out, US Embassy officials in Azerbaijan have expressed the belief that Ziya Mammadov had an ongoing business relationship with an Iranian construction company, Azarpassillo, which shows many of the hallmarks of being a front for the Revolutionary Guard.
