Conservative author Ann Coulter confirmed Wednesday that she advised President Trump against hiring his family members for any key positions in the White House, after failing to get any of his closer associates to do it.

New York magazine on Wednesday published an excerpt from a new book on the White House by Michael Wolff, which includes an anecdote during Trump's presidential transition period when he considered hiring his son in law Jared Kushner as his chief of staff.

"Nobody is apparently telling you this," Coulter told Trump, according to the book. “But you can’t. You just can’t hire your children.”

Coulter corroborated the detail in an email to the Washington Examiner, saying that she only told Trump directly after she was unsuccessful in getting campaign chairman Steve Bannon, billionaire entrepreneur Peter Thiel, and now-White House policy adviser Stephen Miller to do it.

"I tried to get Bannon, Miller or Thiel to tell Trump, but they all said, 'above my pay grade,'" she said. "So I told him. I said only Third Worlders become leader of a country and immediately hire their relatives and he’d look like Evita Perón."

Coulter's commentary against mass immigration is believed to have been a big influence in Trump's campaign.

Trump eventually settled on then-Republican National Committee Chairman Reince Priebus to serve as his first chief of staff. He did, however, hire Kushner and his daughter Ivanka to work as advisers in the White House.
