Donald Trump plans to re-evaluate his position on mass deportation to determine a "fair and humane way" to deal with illegal immigrants living in the U.S., the Republican presidential nominee's campaign manager said Sunday.

"What he has said now is that he will look at that," Kellyanne Conway told Fox News' Chris Wallace. "We need to have a fair and humane way of addressing the fact that ... 11 million, or so it's estimated, illegal immigrants live among us."

Despite Trump's previous calls for the development of a deportation force that would return illegal immigrants to their countries of origin, Conway said he is likely change his position to relying on existing law enforcement agencies to handle deportations.

"The deportation force — I'd like to address that — he hasn't mentioned that since last November, [and] I think in a few of the debates," she added.

"The softening is more approach than policy," she told Wallace, noting that Trump will not propose a pathway to citizenship for those living in the country illegally. "What he has said is no legalization and no amnesty."

She continued, "He also said this week … if you go back to your home country and if you'd like to come back to the United States as an immigrant, you need to apply through the many different channels that allow people to apply for citizenship or entry into the United States legally."

Conway's remarks come on the heels of increasing questions about the billionaire's position on immigration, an issue that has been at the core of his campaign since he launched his White House bid last June.

"There could certainly be a softening, because we're not looking to hurt people," Trump told Fox News' Sean Hannity during a town hall last week.
