“Illegal migration costs the United States $ 300 billion annually,” Trump wrote on Twitter.

Illegal Immigration costs the USA over 300 Billion Dollars a year. There is no reason for this, and things are being set in motion to have this number come WAY DOWN. Democrats could end Loopholes and it would be a whole lot easier, and faster. But it will all happen anyway! ....

The President noted that everything is going to ensure that this figure decreases.

He also called trade deals not properly concluded as one of the country's problems.

.... VERY stupidly negotiated Trade Deals, and Illegal Immigration, are a tremendous cost and burden to our Country. They are BOTH coming along very well and someday, in the not too distant future, America will see a very positive change. Remember, America First!
