Congress has resolved a standoff over the Department of Homeland Security after a retreat by the Republican leadership. The agency nearly shut down last week as Republicans sought to link its budget to reversing President Obama’s executive actions on immigration reform. But on Tuesday, House Speaker John Boehner backed down and brought a “clean” spending bill to the House floor, paving the way for its passage with majority support from Democrats. The measure funds the DHS through the end of the year.
