Five minutes away, Donald Trump Jr. is hosting his own invite-only gathering. The competing parties land at an awkward moment for Melania Trump, whose $40 million documentary is already facing a chilly reception. Hosting there on the same night as Melania’s premiere plants Trump Jr. firmly at the center of his own ecosystem, adjacent to the brand, but not subordinate to it. By the end of the night, Melania may have her premiere. Trump Jr. will have his crowd.
