One of the hallmarks of President Donald Trump's campaign rhetoric was repealing and replacing ObamaCare.

Now that he's in the Oval Office, Trump says he's still committed to getting rid of the Affordable Care Act, but it may take longer than expected.

During an interview with Bill O’Reilly on the Fox Super Bowl pregame show, Trump was noncommittal when asked if Americans can expect ObamaCare to be replaced within the calendar year.

"I would like to say, by the end of the year, at least the rudiments, but we should have something within the year and the following year," Trump said.

He said that it’s “very complicated,” but urged Americans to remember that “ObamaCare is a disaster.”

On "America's Newsroom" today, Doug McKelway reported that the Affordable Care Act will be particularly difficult to dismantle because it is 1,900 pages long, with 20,000 pages of regulations.

"Republicans also see great political risk in repealing without a substantial replacement at the ready, because they know Democrats will launch a huge public relations campaign," McKelway said.

He said that the Trump administration remains committed to eliminating some of the worst features of the health care law, such as the individual mandate, taxes and penalties.
