President Donald Trump said Friday if lawmakers do not fund the border wall, he will shut down the U.S.-Mexico border.

He called Democratic members of Congress "obstructionists." The President has requested $5 billion to pay for the 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. Hard to believe there was a Congress & President who would approve! — Donald J. Trump (@realDonaldTrump) December 28, 2018

....The United States looses 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.” We build a Wall or..... — Donald J.

.....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! — Donald J. Trump (@realDonaldTrump) December 28, 2018

President Trump continued to blame Democrats for the current government shutdown, which has lasted for a week and affects roughly 25 percent of the federal government. As he blasted them as obstructionists on Twitter, and he referenced the recent killing of a California police officer, allegedly by a suspect who is in the country illegally, as a reason to bolster his push for more border wall funds.
