Trump threatens to 'close the Southern Border entirely' if Democrats won't fund his wall

President Donald Trump threatened to shut down the U.S.-Mexico border if Democrats did not cave to his demands in the government shutdown.

The president tweeted out the threat, which he's made before, Friday morning as federal employees remained unpaid and off-duty in a government funding dispute related to Trump's proposed border wall.

"We will be forced to close the Southern Border entirely if the Obstructionist Democrats do not give us the money to finish the Wall & also change the ridiculous immigration laws that our Country is saddled with," Trump tweeted. "Hard to believe there was a Congress & President who would approve!"

"The United States looses [sic] soooo much money on Trade with Mexico under NAFTA, over 75 Billion Dollars a year (not including Drug Money which would be many times that amount), that I would consider closing the Southern Border a 'profit making operation,'" Trump tweeted. "We build a Wall or close the Southern Border. Bring our car industry back into the United States where it belongs. Go back to pre-NAFTA, before so many of our companies and jobs were so foolishly sent to Mexico."

"Either we build (finish) the Wall or we close the Border," he added. "Honduras, Guatemala and El Salvador are doing nothing for the United States but taking our money. Word is that a new Caravan is forming in Honduras and they are doing nothing about it. We will be cutting off all aid to these 3 countries - taking advantage of U.S. for years!"
