US Senate advances on healthcare, with dramatic return by McCain

U.S. Senate Republicans narrowly agreed on July 25 to open debate on a bill to end Obamacare, but the party's seven-year effort to roll back Democratic President Barack Obama's signature healthcare law still faces significant hurdles.

The Senate deadlocked 50-50 on moving forward with the healthcare debate, forcing Vice President Mike Pence to cast the tie-breaking vote.
