President Trump on Monday again threatened to close the southern border.
"We would save Billions of Dollars if the Democrats would give us the votes to build the Wall," Trump tweeted. "Either way, people will NOT be allowed into our Country illegally! We will close the entire Southern Border if necessary. Also, STOP THE DRUGS!"
This was only one of many tweets the president has posted on the matter. 
"Mexico should move the flag waving Migrants, many of whom are stone cold criminals, back to their countries," Trump tweeted last week. "Do it by plane, do it by bus, do it anyway you want, but they are NOT coming into the U.S.A. We will close the Border permanently if need be. Congress, fund the WALL!"
The tweets echo his remarks to reporters on Thanksgiving Day about shutting down the entire border if the migrant situation gets out of control, reports Slate.  "If we find that it's uncontrollable…it gets to a level where we are going to lose control or where people are going to start getting hurt, we will close entry into the country for a period of time until we can get it under to control," Trump said.   He confirmed that he meant "the whole border."
