President Obama admits his biggest mistake of 2013 during end-of-the-year speech

2013 has been a tough year for President Obama. Some are even calling it the worst year of his presidency. The president was drilled with questions from reporters and opened up about his biggest mistake during his end-of-the-year news conference on Friday (Dec. 20).

During his speech, President Obama addressed his low polls, the economy, Obamacare, the nation's "broken immigration system," and the NSA surveillance program.

The president started things off on the up saying, "In 2013 our businesses created another 2 million jobs, adding up to more than 8 million in just over the past 45 months." He noted that it was the "strongest pace in nearly two years."

President Obama also mentioned that the unemployment rate is at "its lowest point in five years," and that deficits are less than half of what they were when he first took office.

Once the president wrapped up his speech, reporters began firing off questions. ABC's Jon Karl asked the million dollar question: what do you think has been your biggest mistake?

Earlier in his speech the president he wished that "Congress had moved more aggressively" in passing background checks after the Newtown tragedy, and that their failure to do so "was a mistake," but President Obama actually considers the health care rollout his biggest slipup.

Here's what he had to say:

"Well, there's no doubt that when it came to the health care rollout...emphasizing how important it was that consumers had a good experience, an easy experience in getting the information they need and knowing what the choices and options were for them to be able to get high-quality, affordable health care, the fact is it didn't happen in the first month, the first six weeks, in a way that was at all acceptable. And since I'm in charge, obviously, we screwed it up."
