In his 2018 budget plan, President Trump proposed adopting paid parental leave nationwide, requiring states to give workers up to six weeks off when having or adopting a child. The new program would cost about $19 billion over a decade, and individual states would have a lot of room to decide how they institute it. However, Congress still has to approve the budget, and many Republicans aren't yet on board with a new social program, while experts warn that it's not enough for new parents.
