President Obama acknowledged Monday that the Web site created to handle enrollments for his landmark health-care law "hasn't worked as smoothly as it was supposed to work," and he pledged that his administration would fix the problems.

"The problem has been that the Web site that's supposed to make it easy to apply for and purchase insurance  -- there's no sugar-coating it, the Web site is too slow," Obama said during remarks in the Rose Garden. "Nobody's more frustrated than I am. I want the cash registers to work."

Flanked by ordinary residents and small business owners who stand to benefit from the Affordable Care Act, the president aimed to restore public confidence in the online application portals for the federal health-care law.

"We're doing everything we can possibly do to get the Web site working faster, better," he said. "People are working overtime to boost capacity. ... Nobody's madder than me, which means it's going to get fixed."
