"The idea of tracking down and deporting 11 million people is absurd, inhumane, and un-American. No, Trump," Clinton wrote
Clinton's comment came after Trump suggested during an interview on MSNBC's "Morning Joe" earlier Wednesday that he would support a "deportation force
"We have to do what we have to do," Trump said. "Other people have done it.
"You're going to have a deportation force. You're going to do it humanely," Trump said, when pressed about how he would deport people who are in the U.S. illegally.
Other candidates took a different tact during the fourth Republican presidential debate Tuesday night, including Ohio Gov. John Kasich, who called Trump's deportation proposal "silly."
"We all know you can’t pick them up and ship them … back across the border," Kasich said. "It’s a silly argument. It is not an adult argument. It makes no sense."
Former Florida Gov. Jeb Bush also took a different approach to illegal immigration, while Sen. Marco Rubio (R-Fla.) stayed out of the discussion until Wednesday.
"If you haven't been here very long, or you're a criminal, you will be deported," Rubio said during an interview on NPR's "Morning Edition."
"Otherwise, you will have to come forward, pass the background check, learn English, pay a fine, because you violated the law, start paying taxes, and you'll get a work permit. And that's all you're going to have for at least a decade," he said.
"After 10 years on the work permit, I personally am open to — after the 10 years have expired — to allowing people to apply for a Green Card, just through the normal process that anyone else would use," Rubio added.
