Spain has agreed to accept aid that may total as much as $125 billion as it scrambles to stabilize its banks. On Saturday, the country became the fourth euro-zone nation to ask for a bailout as the 17 nations that share the common currency continue to fight off spreading debt. Politicians and finance ministers in Europe and America have urged Spain to accept a bailout package in recent weeks, hoping to bring some calm to the continent before Greek elections are held later this month, with President Obama urging quick action in a speech Friday. Spain is the largest country to request a bailout to date.
