Jim Acosta thought he would travel to the border and show the lack of a migrant horde storming the border to show that President Trump is wrong when he claims a national emergency. Instead the Acosta video proves the President's point because Acosta went to a portion of the border which included barriers. As CNN's Acosta walked along in the middle of the day he saw no hordes, no illegals, no national emergency in his words.
Trump and other pundits jumped on Acosta's huge mistake almost immediately on Twitter and Facebook.
