Republican presidential candidate Donald Trump on Wednesday indicated that he would use a “deportation force” to execute his plan of removing more than 11 million undocumented immigrants living in the United States when pressed on how he would execute a mass deportation.

Trump was initially asked about his immigration plan Wednesday morning and then pressed by MSNBC’s Mika Brzezinski on whether the plan is truly practical.

“Okay, conceptually, I understand what you're saying and what you’re describing. But still tell me the how. Are you going to have a massive deportation force?” Brzezinski asked.

Trump responded affirmatively: “You're going to have a deportation force, and you're going to do it humanely, and you’re going to bring the country — and, frankly, the people, because you have some excellent, wonderful people, some fantastic people that have been here for a long period of time.”

The U.S. Immigration and Customs Enforcement agency currently handles deportations. Trump added that he will also build "a real wall" along the U.S.-Mexico border to keep undocumented immigrants from entering the country in the future.

“Don't forget, Mika, that you have millions of people that are waiting in line to come into this country, and they’re waiting to come in legally,” he continued. “And I always say the wall, we're going to build the wall. It's going to be a real deal. It’s going to be a real wall.”

Trump's call for a mass deportation has been met with resistance by several of his rivals for the GOP presidential nomination, namely former Florida governor Jeb Bush and Ohio Gov. John Kasich.

“If people think that we are going to ship 11 million people who are law-abiding, who are in this country, and somehow pick them up at their house and ship them out to Mexico…We all know you can't pick them up and ship them across, back across the border,” Kasich said during Tuesday night's debate. “It's a silly argument. It is not an adult argument. It makes no sense.”
