Senate Minority Leader Harry Reid (D-Nev.) reiterated Monday that Democrats plan to block the formation of a conference committee on Department of Homeland Security (DHS) funding.

Congress passed a one-week DHS bill on Friday. House Republicans want to use the additional time to work out a final spending deal in conference that would roll back President Obama’s executive actions on immigration.

{mosads}”This push by House Republicans to go to conference is the very definition of an exercise in futility,” the Nevada Democrat said. “They want to turn it into something that cannot pass. …. We will not be a party to yet another charade by House Republicans.”

Senate Democrats joined Republicans last week in approving a “clean” bill that would fund DHS through Sept. 30 while keeping Obama’s immigration orders intact. They say the House should pass the same bill.

Conservative Republicans, however, have balked at passing legislation that does not defund Obama’s actions.

The House on Friday approved a motion to go to conference with the Senate on DHS funding.

The Senate will vote Monday at 5:30 p.m. on a procedural motion on legislation setting up a conference with the House on DHS funding. Democrats are expected to block the motion.
