(NewsNation) — Republican President-elect Donald Trump has said he will take a hard-line stance on immigration once in office, including enacting mass deportations of unauthorized migrants.

Morgan Ortagus, a former State Department spokeswoman in the Trump administration, said there are various policies one can expect the former president to follow through on in his second term.

However, there are other indicators for how Trump will deal with the southern border as president, such as who he picks to be Secretary of the Department of Homeland Security, Ortagus said.

“We know that he’s going to want to try and to finish the wall,” Ortagus said, adding that Trump will also likely take on the controversial CBP One app. “If you’re circumventing the legal process, whatever the policy is, I think you can likely expect a second Trump term to not allow policies that are actually circumventing the law.”
