First Lady Melania Trump bad-mouthed stepdaughter Ivanka Trump while being taped by former best friend and adviser Stephanie Winston Wolkoff. Wolkoff details the rivalry between Melania and Ivanka in her new book.

Wolkoff revealed Melania initiated a plan called “Operation Block Ivanka” to prevent the president’s daughter from being pictured in the best inauguration photos.

Wolkoff wrote, “It was Donald’s inauguration, not Ivanka’s, but no one’s brave enough to tell her that. Melania was not thrilled about Ivanka’s steering the schedule and would not allow it.”

Ivanka texted Wolkoff a picture of former President Barack Obama‘s inauguration and commented, “It is nice to have family with him for this special moment.”

Ivanka’s text fueled “Operation Block Ivanka” where the Trump family’s positions were rearranged,  so Melania and Ivanka did not have to stand next to one another.

Wolkoff wrote, “Operation Block Ivanka was petty. Melania was in on this mission. But in our minds, Ivanka shouldn’t have made herself the center of attention in her father’s inauguration.”
