Story highlights President Donald Trump's administration is ending Deferred Action for Childhood Arrivals

The President's move leaves open the window for Congress to save it in six months

But Republicans are divided on how best to address immigration

(CNN) President Donald Trump on Tuesday threw the fate of 800,000 recipients of the Deferred Action for Childhood Arrivals program over to Capitol Hill, where Republican leaders and lawmakers will now have to decide where their party stands on immigration once and for all.

Attorney General Jeff Sessions announced that the Trump administration will end with a six-month delay the DACA program that began under for President Barack Obama. The Trump administration will roll back DACA in March in hopes that Congress can find a legislative solution. However, that is not much time to protect young immigrants who were brought to the country illegally as children, but have had an opportunity to live, study and work in the United States without fear of deportation under the program.

Anything Congress comes up with in upcoming months will have to be bipartisan -- a tough climb in an era when partisanship has gripped Capitol Hill. Even with Republicans in control of the executive and legislative branches of the federal government, getting big legislation to Trump's desk appears strenuous -- if not at times impossible.

Ultimately, it's Republicans who are in charge and Republicans who have been dogged by internal schisms on immigration for years now.

Some Republicans, including House Speaker Paul Ryan and Utah Sen. Orrin Hatch, were so concerned about what Congress would be able to accomplish on DACA in a tight timeframe that they urged Trump last week not to end the program at all.
