Donald Trump referred to Latino immigrants as “criminals” and “rapists” and promised his supporters he would deport 11 million undocumented immigrants during his presidential campaign. Now that he is about to move into the White House, he says he is ready to act on his words.

Trump announced a plan Sunday that will deport up to 3 million undocumented immigrants in his first days in the Oval Office. In his first interview since being announced the winner of the 2016 presidential election, Trump told CBS’ “60 Minutes” that under his plan as many as three million undocumented immigrants with criminal records would be deported or incarcerated.

“What we are going to do is get the people that are criminal and have criminal records, gang members, drug dealers, where a lot of these people, probably two million, it could be even three million, we are getting them out of our country or we are going to incarcerate,” Trump said. “But we’re getting them out of our country, they’re here illegally.”

Trump left the door open on the fate of the millions of other undocumented immigrants in the country Sunday, saying that once the United States’ borders are “secure,” immigration officials would begin “to make a determination” about other undocumented immigrants. Trump had previously pledged that he would deport every single undocumented immigrant in the country, using an armed deportation force to accomplish this goal, Politico reported.

Trump has also pledged to build a wall along the U.S.-Mexico border that could cost up to $25 billion. He said Sunday he is still figuring out how the wall would work. 

“For certain areas I would (build a fence) but certain areas, a wall is more appropriate,” Trump told “60 Minutes.” “I’m very good at this, it’s called construction.”

A group of Roman Catholic Bishops urged Trump Monday to adopt humane policies towards refugees and immigrants.  They said welcoming people fleeing conflict, violence and battle is part of their identity as Catholics.

There are roughly 11.7 million undocumented immigrants living in the United States. Mexican immigrants made up 52 percent of all undocumented immigrants in 2014, according to a Pew Research report. There were 5.8 million undocumented Mexican immigrants living in the U.S. in 2014, compared to 6.4 million in 2009.
