(CNN) Trump transition officials held a conference call with House Ways & Means Committee staff Thursday to make clear that the President-elect and Ivanka Trump want to push their childcare reform proposal through a broader tax reform package in Congress, a Trump transition source told CNN.

The Trump proposal, which includes a childcare tax credit and six weeks of maternity leave protection, carries a hefty $300 billion price tag.

The phone call with Ways & Means staffers is aimed at making clear that this is a top priority on the President-elect's agenda and to begin finding ways to pay for the proposal to make it budget neutral.
