President Trump thought son-in-law Jared Kushner was doing such a bang-up job as a senior adviser that he contemplated naming him secretary of state, the book “Fire and Fury” claims.

Kushner, 36, was given a broad portfolio of responsibilities by Trump, including bringing peace to the Mideast, reforming the criminal-justice system and solving the opioid crisis — despite his lack of political or policy experience.

In the book, author Michael Wolff writes that White House Chief of Staff John Kelly wanted to find a way to ease Kushner and his wife, first daughter Ivanka Trump, out of the White House.

So he decided to broach the subject of Kushner and Ivanka with Trump, the book says.

“It was all intended to be a politic way of opening a discussion about getting them out,” Wolff wrote.

“But the president was, Kelly soon learned, delighted with all aspects of their performance in the West Wing. Maybe at some point Jared would become secretary of state — that was the only change the president seemed to foresee.”
