Trump, who promoted child care and family leave policies during her father's campaign, also told reporters that child care "is going to be part of comprehensive tax reform."Before the event, the president tweeted that he is "proud of @IvankaTrump for her leadership on these important issues."The 35-year-old Trump stepped away from both running her fashion brand and from an executive role at the Trump Organization to become an unpaid White House adviser, but she continues to own her lifestyle brand, which allows her to profit off her rising profile and has prompted criticism from ethics experts.

She said she was "humbled to be here with so many formidable leaders" and would bring their advice and knowledge back to her father.

"This is very early for me; I'm listening, I'm learning, I'm defining the ways in which I think that I'll be able to have an impact," Trump said.
