In an interview published this week, Florida Sen. Marco Rubio shared his strong views on immigration, which differ immensely from his previous position.

According to Breitbart News Network, just over a year ago, Rubio worked with Sen. Chuck Schumer, D-NY, to pass "a comprehensive immigration bill that would grant citizenship to millions" of undocumented immigrants.

Now, however, the Republican senator is against "comprehensive" reform.

On Tuesday, Rubio sent a letter to President Barack Obama detailing his move from comprehensive reform. Instead, he recommends securing the border with "strategic sensing, cameras, more personnel on the border ... E-Verify ... an entry-exit tracking system to find those who entered legally and end up being here illegally because they overstayed visas."

Rubio also wants to create a process toward citizenship that takes years to complete and is based on merit, where immigrants are allowed into the country "primarily on the basis of skill and talent, not on the basis of whether they have a relative living here."

"I continue to believe our system needs to be reformed and I've learned in the last year that because of such an incredible distrust of the federal government no matter who's in charge, the only way you're going to be able to deal with this issue is by first securing the border and ensuring that illegal immigration is under control," Rubio said.

The senator is strongly against Obama taking executive action to solve the immigration crisis, saying that it would delay reform.

"It would just further exacerbate people's lack of confidence in the government's willingness to enforce the law, and I also think it would continue to add to the ambiguity of the laws that have created the humanitarian crisis that now exists on the border with unaccompanied minors," he explained. "That's not me saying it. It's the presidents of Guatemala and Honduras, when they came to Washington a few weeks ago ..."

In addition, Rubio criticized the Deferred Action for Childhood Arrivals program, which went into effect in 2012. The program delays deportation for those who came to the country as children and have lived in and attended school in the country since 2007. The senator believes that program should not "be the indefinite policy of the United States."

"I'm willing to be reasonable about when it comes to an end, whether it be two years, one year, six months, three [years], but it has to come to an end," he said.

Rubio is a potential 2016 presidential candidate but has not officially decided if he will run yet.
