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.
