2 Republicans depart House immigration group  ERICA WERNER
Associated Press Published:  WASHINGTON (AP) -- Two Republicans
have announced plans to leave a bipartisan House group that's
been working in secret to write a comprehensive immigration
bill.  Texas Reps. John Carter and Sam Johnson say they can no
longer be part of the effort because they don't trust President
Barack Obama to enforce any legislation they write.  It leaves
Rep. Mario Diaz-Balart of Florida as the sole Republican with
four Democrats in the group. It's the latest sign of the
difficulties of reaching any deal on immigration.  However, the
House group had delayed its bill for months, raising questions
about its relevance. House Republican leaders have said they
plan to proceed with immigration legislation on a step-by-step
approach, not with a single big bill like the group has been
trying to produce.
