President Donald Trump boasted that he is building a “beautiful wall” — “a big one that really works” — on the border in New Mexico, and apparently in the state north of New Mexico as well.

During remarks at an energy conference on Wednesday, Trump said, "We're building a wall on the border of New Mexico and we're building a wall in Colorado."

RawStory noted that social media users were quick to respond to the president’s error, writing, “It prompted many to wonder if the president whipped out his fact-changing Sharpie yet again.”
