U.S. House Speaker Ryan rules out work with Obama on immigration

House of Representatives Speaker Paul Ryan on Sunday ruled out working with President Barack Obama on overhauling U.S. immigration policy, saying it would be "a ridiculous notion" to pursue legislation because Obama cannot be trusted on the issue. The immigration issue has driven a wedge between Hispanics, an increasingly important voting bloc, and Republicans, many of whom take a hard line on illegal immigration, to the benefit of Obama's fellow Democrats. Most of the estimated 11 million illegal immigrants in the United States are Hispanic. Ryan, a Wisconsin Republican chosen as speaker on Thursday to replace the retiring John Boehner, said he would not try to advance comprehensive immigration legislation while Obama, whose term ends in January 2017, is president.
