President Biden's plan to cancel billions of dollars of student loan debt appears in jeopardy.

• During oral arguments today in two cases challenging the plan, the Supreme Court's conservative majority appeared skeptical that he has the legal authority to offer the far-reaching debt relief, Axios' Erin Doherty reports.

Chief Justice John Roberts and other conservative justices invoked the "major questions doctrine," which holds that the executive branch needs explicit congressional approval to act on the biggest issues.

• The court has used that doctrine lately to strike down several Democratic priorities, including environmental regulations and COVID vaccine mandates.

Solicitor General Elizabeth Prelogar argued that the plan was legal under the HEROES Act of 2003, which allows the education secretary to "waive or modify" student financial assistance programs when there's a national emergency.

• Both former President Trump and Biden have used the statute to pause student loan payments since the outset of the COVID pandemic.

Since Biden announced the plan last August, 26 million people applied for student loan debt relief. More than 16 million of those borrowers' applications were fully approved.

• The program has been on hold since November, after a Texas judge struck it down.

More than 120 countries provide some sort of guaranteed paid parental leave for fathers — up from 46 countries in the 1990s, according to a report from the World Policy Analysis Center.

• The U.S. isn't one of them.

Though support is growing for paternity leave, there's still a stigma attached to men who take time off to care for their children. Yet studies find that leave provides numerous benefits for the economy, for fathers and for their partners, Axios Markets co-author Emily Peck writes.

• The U.S. is also one of just seven countries in the world that does not guarantee paid maternity leave.
• The other countries are the Marshall Islands, Micronesia, Nauru, Palau, Papua New Guinea and Tonga.
