(CNN) Ivanka Trump met privately Tuesday morning for about an hour with Sen. Marco Rubio and other lawmakers on the Capitol Hill to discuss "pro-family" tax reform.

Members of Congress have been invited to join the new duo over the coming weeks to talk about Trump's proposal for a federal paid family leave program , which would grant families six weeks paid leave. The proposal, however, has struggled to gain support from conservatives and liberals.

"Just left a productive meeting on the Hill to discuss issues affecting American working families, including childcare & paid family leave!" Trump tweeted.

"She's expressed a strong interest in many different elements that I think comprise a pro-family tax reform. We wanted her and the White House to be exposed to individual members who have been working on pieces that I think can be part of that reform," Rubio, who is particularly focused on the child tax credit, said. "And we'll see what the next step is, but it's certainly something we're going to continue to work on."

Nebraska Rep. Deb Fischer, who introduced a bill this year to give tax credits to companies offering paid maternity and paternity leave, participated in Tuesday's meeting, along with Iowa Sen. Joni Ernst, South Carolina Sen. Tim Scott and Utah Sen. Mike Lee.
