Washington (CNN) Former Vice President Joe Biden criticized the involvement of President Donald Trump's family members in the White House, saying his own children "are not going to have offices in the White House" if he is elected president.

During an interview with CBS' "60 Minutes" set to air Sunday, the 2020 Democratic presidential candidate called the senior administration roles of Trump's daughter Ivanka Trump and her husband, Jared Kushner, "improper." Trump has repeatedly criticized Biden's son Hunter , who sat on the board of a Ukrainian natural gas company while his father was in charge of the Obama administration's Ukraine policy. There is no evidence of wrongdoing by either Biden in Ukraine.

"Look, I wasn't raised to go after the children. Their actions speak for themselves. I can just tell you this, that if I'm president -- get elected president my children are not going to have offices in the White House," he told "CBS Evening News" anchor Norah O'Donnell when asked if he believes Trump's children have acted properly and avoided conflicts of interest. "My children are not going to sit in on Cabinet meetings."

He added: "It's just simply improper, because you should make it clear to the American public that everything you're doing is for them."

Biden also said the President's children should not be engaged in the "day-to-day operation they know nothing about" and said Kushner should not be negotiating a Middle East peace plan.
