WASHINGTON (AP) — Republican leaders want to stage a climactic vote on their health care bill next week. But internal rifts over issues like coverage requirements and Medicaid cuts leave the timing and even the measure’s fate unclear.

Cornyn cited seven years of unresolved Republican debate over how to replace the 2010 statute. That underscored a sense among top Republicans that they had little to gain by letting their disputes drag on much further.

Consensus on a replacement seemed more remote than ever as senators returned from July 4 recess.
