Ivanka Trump, who serves as an adviser to her father, President Donald Trump, has described the administration's family-separation immigration policy as "a low point" of her tenure in the West Wing.

"That was a low point ... I feel very strongly about that," Trump said Thursday morning at an event hosted by the news website Axios.

Ivanka Trump, who serves as an adviser to her father, President Donald Trump, has described the administration's family-separation immigration policy as "a low point" of her White House tenure so far.

"That was a low point ... I feel very strongly about that," Trump told Axios' executive editor, Mike Allen, at an event hosted by the news website on Thursday morning. "I am very vehemently against family separation and the separation of parents and children."

She reportedly urged her dad to end the policy, in which all adults detained at the border on immigration offenses were criminally prosecuted, requiring them to be separated from any children accompanying them.

While decrying the policy, which the administration has walked backed from, Trump described the issue of immigration as "incredibly complex" and "incredibly complicated." But she also said the US was "a country of laws."

"We have to be very careful about incentivizing behavior that puts children at risk of being trafficked, at risk of entering this country with coyotes or making an incredibly dangerous journey alone," Trump said. "These are not easy issues — these are incredibly difficult issues — and like the rest of the country I experience them in a very emotional way."

Trump mentioned that her mother, Ivana, immigrated to the US from the Czech Republic (then communist Czechoslovakia).

At the same, Trump said "seeing Alice Johnson leave prison and run into the arms of her family" had been a high point. After lobbying by Kim Kardashian, Trump's father granted clemency to Johnson, a 63-year-old grandmother who was serving a life sentence for nonviolent drug offenses, in June.
