On Tuesday, the Senate voted in favor of a motion to proceed to debating the House-passed health-care bill. The motion passed 50-50 with Vice President Mike Pence stepping in to break the tie. Sens. Susan Collins (Maine) and Lisa Murkowski (Alaska) were the only Republicans to vote against the measure; Sen. John McCain (R-Ariz.), who is undergoing treatment for brain cancer, returned to Washington to cast his yes vote amid a round of applause. No Democrats voted in favor. Lawmakers will now move to 20 hours of debate on health-care proposals, including the Senate's Better Care bill and a straight repeal bill favored by conservative Sen. Rand Paul (R-Ky.). A "skinny repeal" plan, which was introduced just hours before Tuesday's vote and would center around eliminating ObamaCare's individual mandate, could also come into play.
