WASHINGTON (Reuters) - Senator John McCain will make a return to the U.S. capitol on Tuesday to play what could be a crucial role in keeping Republican efforts to repeal Obamacare afloat.

McCain, who is battling brain cancer at his Arizona home, is set to help decide whether the repeal push will move forward or perhaps be abandoned entirely.
