The new Congress has only just begun and Republican leaders are already debating how to handle a looming shutdown fight over immigration. Funding for the Department of Homeland Security expires February 27 and conservatives want any new legislation extending the department’s cash line to include language stopping President Obama’s plan to protect millions of undocumented immigrants from deportation. The White House indicated last month that it would veto measures blocking the president’s executive action, which would lead to a partial government shutdown if Congress doesn’t back down. Speaker John Boehner headed off a larger shutdown in December by passing legislation funding the government through September, except for DHS, which handles immigration enforcement among other things. At the time, he argued Republicans would be in a better position to win a fight once the new GOP Senate was sworn in. On Thursday, he assured members that his plan to challenge Obama has not changed, even in the wake of a terrorist attack on Paris that’s put national security issues back on the front page.
