Facing a major debt deadline, Puerto Rico on Tuesday scrambled to free up $355 million to stave off a default. In addition, the governor announced an unprecedented plan that would take money from one group of bondholders to pay another.

"Starting today, the commonwealth of Puerto Rico will have to claw back revenues pledged to certain bonds issued in order to maintain essential public services," Gov. Alejandro Garcia Padilla said at a Senate Judiciary Committee hearing. "We have taken this difficult step in the hope that Congress will act soon."
