"We're evaluating why it is exactly that I didn't know soon enough that it wasn't going to work"

“Obviously my most recent concern has been that my website’s not working,” Obama said. “We’re evaluating why it is exactly that I didn’t know soon enough that it wasn’t going to work the way it needed to. But my priority now has been to just make sure that it works.”

The glitches aside, Obama remained confident the Affordable Care Act, passed along party lines in 2010, would form a large part of his presidential legacy.

“I continue to believe and I’m absolutely convinced that, at the end of the day, people are going to look back at the work we’ve done to make sure that in this country, you don’t go bankrupt when you get sick, that families have that security,” Obama told Walters. “That is going be a legacy I am extraordinarily proud of.”
