Sen. Marco Rubio, R-Fla., and presidential adviser Ivanka Trump are reportedly collaborating on a paid leave plan. Though no official policy has been rolled out, Rubio supports a so-called “conservative” version of paid family leave: giving new parents the option to delay their Social Security payments and draw benefits while at home with a newborn.

But this plan is not conservative at all. Instead, it expands an overburdened entitlement program that desperately needs to be reformed.
