Ivanka Trump said Wednesday that Hillary Clinton has had a lifetime to help parents with childcare costs, and nothing has happened.

'You know, respectfully, Hillary Clinton has been around for decades, and there's no policy benefiting mothers or fathers in terms of paid leave,' Donald Trump's power-player daughter said on 'Good Morning America.'

She helped her father roll out an ambitious plan Tuesday night that would let American parents deduct the cost of daycare and elder-care from their incomes before paying taxes.

Ivanka Trump said Wednesday that Hillary Clinton has had 'decades' to help American parents with childcare costs, but hasn't come through

Ms. Trump said on 'Good Morning America' that Clinton 'could have' helped with a plan like her father's

And despite a website promising a plan similar in some ways to Donald Trump's, she sad, Clinton has had plenty of chances to deliver results.

The Democratic presidential nominee has been America's first lady, a U.S. senator, and secretary of state.

'Certainly she had opportunity to have a concept like that,' Ivanka said.

'We have not been in public office for the last several decades, and she has. So she could have instituted some of those policies in that role and has not done so.'

Ivanka introduced her father Tuesday night in Pennsylvania before he rolled out a tax-deduction plan intended to offset childcare costs for working parents

Ivanka introduced the Republican nominee Tuesday night in a suburb of Philadelphia.

'We took a giant leap forward with the plan,' she said on ABC.

'I think the fact that we are advocating for this, and advocating for it so strongly, and taking leadership on this issue is testament in itself to our thoughts on this subject.'

She called childcare costs 'the single greatest household expense in much of the country, exceeding even the cost of housing. A lot of people don't realize that.'

And she explained that if Donald Trump becomes president, she and her brothers Eric and Don Jr. – who would run the family business – would have the flexibility to avoid conflicts of interest that might plague a public company because of bottom-line concerns.

'There's something so much bigger than our business at stake ... we can make decisions that are not in our best interest,' she said.
