WASHINGTON, July 15 (Reuters) - U.S. Senator John McCain will remain in Arizona next week to recuperate from a medical procedure that removed a 2-inch (5-cm) blood clot above his left eye, his office announced in a statement on Saturday.
It was unclear how McCain's absence might affect a crucial Senate vote on legislation to dismantle and replace Obamacare, with Republicans so divided that a single vote could doom the bill.
His office was not immediately available to comment on when the lawmaker would return to Washington. (Reporting by David Morgan; Editing by Cynthia Osterman)
