After reports that President Donald Trump will announce Tuesday that he is ending the Deferred Action for Childhood Arrivals Program, known as DACA, Sen. Dean Heller, R-Nev., emphasized that he supports the program.

What is DACA and who does it protect?

DACA, a program created under Barack Obama, protects nearly 800,000 undocumented immigrants who came to the United States illegally before age 16, were under 31, were in school or graduated and did not have a felony conviction. According to Reuters' sources, Trump will give Congress six months to come up with a replacement.

Heller expressed concern with how the DACA program came to be. However, he said he still supports it in a written statement to the Reno Gazette-Journal.

"The DACA program was born out of an executive order from President Obama and it's another example of why it's important that Congress debates and tackles any policy that significantly alters our nation's laws," he said. "While I remain concerned about the way in which DACA came to life, I've made clear that I support the program because hard working individuals who came to this country through no fault of their own as children should not be immediately shown the door."

Heller added, "This is why I am a cosponsor of the Bridge Act, which provides legal status for these individuals while Congress works toward a permanent solution through the proper Constitutional process."

The Bridge Act would provide three-year provisional protection for undocumented immigrants and codify several provisions of Obama's executive order. The bill has bipartisan support.

Heller said: "Just as I have in the past, I'll continue to work with my colleagues to reform our broken immigration system and that must start with securing our borders; however, we cannot lose sight of the fact that our country has a long history of welcoming immigrants and our communities in Nevada are stronger because of it."

Local groups are organizing a rally outside of Heller's Reno office on Tuesday. Organizers said on the Facebook event page, "We need to show up and let Senator Heller, Trump and everyone else that Nevadans stand with our friends, neighbors and loved ones."

The protest is scheduled to start at 10 a.m. Tuesday.
