State leaders on Wednesday will advocate for protecting undocumented immigrants who were brought to the U.S. illegally as children.

U.S. Rep. Jared Polis, D-Boulder; Lt. Gov. Donna Lynne, a Democrat; and Denver Mayor Michael Hancock are among officials who will speak at the event, along with members of the business, education and immigrant communities.

The focus is on the federal Deferred Action for Childhood Arrivals, or DACA, program. The Trump administration has so far signaled that it will keep the program, which allows undocumented immigrants who were brought to the United States illegally as children to remain in the country.

The Obama-era effort allows young immigrants to obtain a driver’s license, legal employment and a Social Security number, among other necessities to reside legally in the United States. Applicants must register with the government, pay a fee, and pass criminal and national-security background checks.

Over 17,000 Coloradans have benefitted from the program, according to a news release announcing the press conference on Wednesday. Over 15,000 DACA recipients are currently working in Colorado. A recent study estimates that Colorado stands to lose more than $856 million in gross domestic product annually from the loss of DACA workers in the state’s economy.

“The Deferred Action for Childhood Arrivals (DACA) program means the difference between openly living and thriving in the only country they have ever known as home, and hiding out in fear of deportation and forcible separation from their family and friends,” said Polis, who is running for governor.

While the Trump administration has not signaled that it would eliminate the program, advocates of DACA point out that the Department of Homeland Security has not committed to defending the program in court if it faces a legal challenge.

The attorneys general of at least 10 states have threatened to sue President Trump if he does not revoke the memorandum that created DACA and announce that his administration will not renew or issue any DACA permits.

The press conference Wednesday is scheduled for 10 a.m. at the Colorado Business Roundtable Offices in Denver.

“These young aspiring Americans deserve a permanent solution, and Congress must act to immediately address the hardship experienced by these dreamers,” Polis continued. “I want them to know that I am on their side, and will continue to advocate for the continuation of the DACA program, and for a permanent solution in Congress.”

Fears continue to swell in immigrant communities over a potential federal crackdown of undocumented immigrants who were not brought to the United States as children.

Hancock is considering an executive order aimed at protecting the immigrant community in the face of a potential federal crackdown. The order would essentially curb the federal government’s reach over arresting immigrants, though questions remain as to how effective it would be against federal immigration officers.

The Denver City Council is separately considering an ordinance that would limit information-sharing with the federal government on undocumented immigrants.

Both efforts would likely put the city at odds with the federal government, which could impact federal funding that Denver receives.

“False hopes is telling Denverites that we are safe and welcoming, while allowing Denver employees to continue communicating with ICE,” said Salvador Hernandez, with immigrant rights group, Mi Familia Vota.

The group pointed out that in the last fiscal year, at least 279 undocumented immigrants in Denver were deported after the Denver Sheriff Department complied with ICE requests.

Meanwhile, U.S. Sen. Michael Bennet, a Democrat, is continuing the push for more to be done around undocumented immigrants who came to the country as children. He is asking President Trump to use his executive authority to protect the DACA program.

Bennet was part of a bipartisan group of lawmakers in the Senate that advanced immigration reform that would allow for a path to citizenship, but the effort stalled over political gridlock.

“DACA has provided relief to thousands of young people in Colorado, allowing them to focus on working hard in school and preparing for their futures,” Bennet said in a statement. “These are individuals who arrived here as children and know no other home than the United States.”
