Stepping up the fight for sweeping immigration reform, AFL-CIO President Richard Trumka on Thursday said that if House Speaker John Boehner and his GOP caucus don’t OK a “path to citizenship” for 11 million illegal immigrants, they will be punished by voters for “decades.”

Promising to bring a world of political hurt on immigration reform foes, Trumka warned the Republican House that its decision on the issue could change the political makeup of the nation.
