President Donald Trump urged Congress to prevent large groups of illegal immigrants from entering the country.

“Act now Congress, our country is being stolen!” Trump wrote on Twitter on Monday morning.

Trump said that “weak” border laws passed by Democrats prevented border patrol and ICE agents from enforcing the border laws.

“Congress must immediately pass Border Legislation, use Nuclear Option if necessary, to stop the massive inflow of Drugs and People,” he wrote.

Trump repeated his views about DACA, saying the issue was “dead” after Democrats refused to make a deal to legalize illegal immigrants brought to the United States as children.

He reminded Mexico that they had the power to prevent large “caravans” of illegal immigrants from entering the country.

“They must stop them at their Northern Border, which they can do because their border laws work, not allow them to pass through into our country, which has no effective border laws,” Trump wrote.

Mexico has the absolute power not to let these large “Caravans” of people enter their country. They must stop them at their Northern Border, which they can do because their border laws work, not allow them to pass through into our country, which has no effective border laws…..

…Congress must immediately pass Border Legislation, use Nuclear Option if necessary, to stop the massive inflow of Drugs and People. Border Patrol Agents (and ICE) are GREAT, but the weak Dem laws don’t allow them to do their job. Act now Congress, our country is being stolen!

DACA is dead because the Democrats didn’t care or act, and now everyone wants to get onto the DACA bandwagon… No longer works. Must build Wall and secure our borders with proper Border legislation. Democrats want No Borders, hence drugs and crime!
