Making a rare return to the political arena, former President George W. Bush urged Congress on Wednesday to reach a “positive resolution” on immigration reform, an issue that eluded him during his presidency and now confronts fellow Republicans in the aftermath of a 2012 election drubbing.

In brief remarks at a naturalization ceremony at his presidential library in Dallas, Bush avoided wading into the merits of specific legislation pending in Congress, but said it was important for lawmakers to recognize the benefits of immigration to the nation’s future. While he didn’t directly endorse a Senate-approved plan his comments suggested the need for Republicans to deal with immigration reform in a broad way.
