The man President-elect Donald Trump tapped to oversee mass deportations is a close ally of Gov. Greg Abbott who developed some of his hardline stances while working as an immigration enforcement officer in Texas.

Incoming Border Czar Tom Homan weighed in on the recent terror incidents in Las Vegas and New Orleans, expressing concerns about national security vulnerabilities and potential connections between the two attacks.

While campaigning for the White House earlier this year, Donald Trump insisted that if elected president he would launch the “largest deportation” in American history. However, there is one major obstacle that could prevent this from happening: a huge backlog in immigration court cases.
