Democrats are holding the Senate floor into Wednesday night to protest the Trump administration to end a key Obama-era immigration program.

President Trump sparked ire from Democrats and some Republicans when his administration announced Tuesday it would phase out the Deferred Action for Childhood Arrivals (DACA) program, which has allowed roughly 800,000 immigrants brought into the country as children to remain legally.

"It's a cold political calculation, and those with money and power have used it time and time and time again to keep us fighting with each other, fighting over religion, fighting over race," she said from the Senate floor. "[Trump] is failing in his basic moral duty to protect these people."

Charles Schumer Senate Minority Leader(D-N.Y.) warned Trump's decision will "rip apart families" and likely have "devastating" economic consequences.

"If we don't see a clean DREAM Act in September. We, as the minority here, are prepared to attach it to legislative vehicles in the fall until it passes. These 'Dreamers' are Americans in their hearts. They ought to become Americans in the books of law as well," he said.

Democrats are expected to hold the Senate floor until at least 10 p.m.

Democrats are demanding that Senate Republicans hold a vote on the DREAM Act this month—a move GOP leadership has dismissed as unlikely.

Dianne Feinstein Sen.(D-Calif.) added lawmakers should stop "playing with their lives."

"This decision to end DACA without first ensuring that young people have legal protection is why we are demanding a vote on the DREAM Act as soon as possible," she said from the Senate floor.

The DREAM Act would allow people brought to the United States illegally as children to continue to live and work freely in the country, similar to DACA.

But Democrats would need GOP support to attach the proposal to any bill in the Senate.

Republicans, while saying they are sympathetic to immigrants currently covered by DACA, want to tie any bill to a push to bolster border security.

The Judiciary Committee will hold a hearing on next week on "the Long-term Impact of Immigration: Exploring Reforms to our Nation’s Guest Worker Programs and Deferred Action for Childhood Arrivals, and their Potential Impact on the American Economy and Local Communities."
