During the first week of May, the Times and WaPo covered the Kushner family's supposed efforts to attract Chinese investors with the promise of US visas.

"The kids" -- Jared and Ivanka -- exhibited an increasingly panicked sense that the FBI and DOJ were moving beyond Russian election interference and into finances. "Ivanka is terrified," said a satisfied Bannon.

His daughter and Son-in-law, their urgency compounded by Charlie Kushner's concern, encouraged him, arguing that the once possibly charmable Comey was now a dangerous and unctrollable player whose profit would inevitably be their loss.

By the time the meeting ended, Bannon and Priebus believed they had prevailed. But that weekend, at Bedminster, the president, again listening to the deep dismay to daughter and son-in-law, built up another head of steam. With Jared and Ivanka, Stephen Miller was also along for the weekend. ... It was Jared, in the version told by those outside the Jarvanka circle, that pushed for action, once more winding up his Father-in-law. With the president's assent, Kushner in this version gave miller notes on why the FBI director should be fired and asked him to draft a letter that could set out the basis for immediate dismissal.

My summation of later writing: Kushner's side says they didn't fight for it or against it.
