Amid calls from Speaker John A. Boehner for Senate Democrats to stop blocking Homeland Security funding, House Minority Leader Nancy Pelosi and Senate Minority Leader Harry Reid pushed back in a joint news conference Thursday, blaming Republicans for the spending impasse. “It’s like eighth grade civics class, I mean what is going on in the House?” Reid asked. “We have the two leaders who haven’t talked to each other in two weeks. This is not a very good situation, and we’re not going to be part of their petty games.” Reid would not get into “hypothetical games” as to whether Democrats would support a short-term continuing resolution to keep the Department of Homeland Security funded, adding the Senate would not go to conference with the House on a bill with riders blocking President Barack Obama’s immigration executive orders. “I think what their demonstrating though is that immigration was not the reason they’re shutting down government, it was the excuse they were using, because now they have an out from what the judge said in Texas and now they still want to shut down government,” Pelosi said. “So understand, shutting down government is their motive.”
