President Donald Trump is announcing today new measures on illegal immigration and national security, including on his plan to build a wall along the U.S. border with Mexico. 

He is also expected to order an end to sanctuary cities and toughen interior enforcement by ICE, which was almost non-existent under the Obama administration.

William La Jeunesse reported this morning on how Border Patrol agents on the ground are viewing the policy changes.

He explained that Trump's plan would end what the agents see as the #1 problem on the border: catch-and-release of people who are apprehended. 

La Jeunesse said most cases involve people from Central America who claim to be seeking asylum from their home countries. 

"Currently, they are released with a bus ticket and a work permit," he explained.

Shawn Moran of the National Border Patrol Council said agents are "encouraged" about Trump ending these policies.  

"We have had eight years of finding excuses and reasons and loopholes to allow people to be walked out the front door of Border Patrol stations," said Moran.
