The Obama administration has hired 40 percent more people to help with healthcare sign-ups in the final week ahead of the 2015 deadline for enrolling in health insurance through ObamaCare. A total of 14,000 people are running call centers across the country starting Monday, when prospective enrollees will have less than a week to meet the Feb. 15 deadline. Officials in charge of HealthCare.gov said they have been planning for a last-minute swell of sign-ups, warning that the wait times for call centers have continued to increase as the clock winds down.
