Facing deep resistance among House Republicans to citizenship for the estimated 11 million immigrants in the country illegally, GOP leaders are trying to muster support for a stripped-down immigration reform bill that would offer citizenship only to those brought into the country as children.

The plan, which would almost certainly be a nonstarter for President Obama and Democrats who control the Senate, makes clear there will be no quick agreement on a Senate-passed bill and illustrates how wide the gap remains over fundamental immigration reform.
