The twinned Trump Towers bear the president-elect’s name in Istanbul. Dogan Holding, a massive media and real estate conglomerate in Turkey, owns the conjoined buildings and pays the Trump Organization to license the Trump name and brand. It can now rely on that name and brand to be sitting in the Oval Office and singing its praises to President Erdogan.

In his call with the Turkish leader, Trump passed on praise for Erdogan from Mehmet Ali Yalcindag, son-in-law of Dogan Holding owner Aydin Dogan and former president of the Dogan Media Group. His wife, Arzuhan Dogan Yalcindage, sits on the board of Dogan Holding. He’s friends with the Trump family and had worked closely on the Trump Towers project in Istanbul. On election night, he attended Trump’s shocking victory celebration at the New York Hilton in Midtown Manhattan.

Trump’s praise for Mehmet Ali Yalcindag was first reported by Amberin Zaman in the independent Turkish paper Diken. Zaman’s report has since been picked up by other Turkish newspapers and television stations.

Vouching for his Turkish business partner in the call with Erdogan is just the most recent sign of Trump’s near-impossible task in avoiding the significant conflicts of interest his global real estate business presents.
