The stalled nomination of Judge Merrick Garland to the Supreme Court is giving President Barack Obama a chance to do what he says he's missed: go back to school.

Obama was returning to the University of Chicago Law School on Thursday to argue his case for why the Senate should give Garland a seat on the nation's highest court. Obama taught constitutional law at the university before he entered politics.

The president chose Garland, a federal appeals court judge, to fill the seat left empty by the February death of conservative Justice Antonin Scalia.

But Republican Senate leaders maintain the nomination is the next president's responsibility and have refused to schedule a committee hearing for Garland,

Garland, meanwhile, has been meeting with Republican and Democratic senators on Capitol Hill.
