President Obama on Thursday will call on congressional Republicans to approve a “clean” funding bill for the Department of Homeland Security that preserves his executive actions on limiting deportations.

During a visit to the House Democratic retreat, the president is expected to seize on a suggestion from some Republicans that they allow funding for the department to lapse if they are unable to secure concessions.

“The president will join the Democrats in Congress in vehemently opposing that dangerous view and calling for a clean funding bill to ensure we are funding our national security priorities in the face of cybersecurity and security threats abroad,” a White House official said.

Obama is looking to press his political advantage over Republican leaders, who have struggled to come up with a deal that could satisfy conservative lawmakers determined to reverse the president’s immigration orders.
