President Donald Trump's daughter and senior adviser Ivanka Trump was once viewed as a moderating influence over him — but after about a year and a half in office, there's no sign that her more liberal instincts are rubbing off on him.

And during an interview at the Newseum Thursday morning, she confirmed what many suspected: She has no interest in taking any concrete steps to make a real difference at the White House.

Jennifer Rubin, a conservative writer for the Washington Post, argued in an op-ed that no one should no longer have any illusions about Ivanka Trump's failure to uphold a standard of moral decency in the White House.

One of the more notable parts of Ivanka Trump's interview on Thursday addressed the immigrant family separation policy the administration recently put in place, triggering a massive outcry. But while she said the policy was a "low point for me," Ivanka Trump failed to take any responsibility for it, saying the issue is "incredibly complicated."

Rubin writes of Ivanka Trump's defense of the policy:

For starters, this is not complicated at all — if one wants to enter the fact-based world. We do not have a border crisis; the zero-tolerance policy was designed to punish migrants and to excite Trump’s base. Not complicated at all. But she is very, very opposed to it, yet not opposed enough to leave the administration, even as hundreds of children remain separated, and not opposed enough to depart from an administration in which officials were directly warned of the potential for significant, lasting psychological harm to the children — and those same officials remain in their jobs.

Rubin also argues that it doesn't appear the president's daughter is actually getting anything substantial by staying at the White House — the paid family leave policy she touted during the campaign isn't going to happen, as she even admitted Thursday morning.

"If she’s holding out for a bill that Republicans and Democrats could pass and her father would sign, she is living in la-la land," Rubin writes.

"Ivanka is no different from any other enthusiastic member of the administration," she continued. "Observers who thought she’d moderate her father were mistaken. Forget it."
