Colorado governor slams Trump after president says America's building the wall there

President Trump caught flak on Wednesday after he boasted -- incorrectly -- that he is "building a beautiful wall" in Colorado, a state that does not border Mexico.

The state's Democratic Gov. Jared Polis mocked Trump for the gaffe on Twitter, saying: "Well this is awkward... Colorado doesn't border Mexico. Good thing Colorado now offers free full day kindergarten so our kids can learn basic geography."
