WASHINGTON (AP) — Republicans are starting to lay the blame on President Barack Obama if an overhaul of the nation's broken immigration system fails to become law.

The GOP's emerging plan on immigration is to criticize Obama as an untrustworthy leader and his administration as an unreliable enforcer of any laws that might be passed.

Perhaps realizing the long odds of finding a consensus on immigration, Republicans have started telling voters that if the GOP-led House doesn't take action this election year, it's Obama's fault.

House Republicans last week unveiled a road map for an overhaul of the nation's broken immigration system. But one of its backers, Rep. Paul Ryan of Wisconsin, tells ABC's "This Week" that distrust of Obama poisons interest in doing anything among some in his Republican caucus.
