Ryan security plan stresses border control, immigration

WASHINGTON (AP) — House Speaker Paul Ryan is proposing to secure U.S. borders by overhauling the immigration system and installing robust defenses to keep out extremists, criminals and drug cartels.

Ryan calls for the use of "high fencing" along border areas, but steers clear of the billionaire candidate's signature issue: building a wall to keep people from illegally entering the United States from Mexico.

Ryan said the U.S. has repeatedly failed to eliminate serious vulnerabilities in the immigration system, citing the inability to verify comprehensively whether visitors to the U.S. actually leave when their visas expire.

In a video posted last week, he made an appeal to frustrated Republican voters who are supporting Trump, the party's presumptive nominee.
