PROVIDENCE, R.I. (AP) — A crowd of carolers singing "O Christmas Tree" has interrupted the annual tree lighting at the Rhode Island Statehouse after Gov. Lincoln Chafee (CHAY'-fee) unwrapped a holiday hubbub by calling the evergreen a "holiday" tree.Chafee presided over Tuesday's tree lighting. He tells The Associated Press that he didn't seek to create controversy. He says the word "holiday" respects the state's founding as a haven for religious diversity. Previous governors have also used the term.The move angered many in this heavily Catholic state. During Tuesday's ceremony, several protesters interrupted a children's choir performance to loudly sing "O Christmas Tree."Ken Schiano attended because he wanted to stand against what he says is Chafee's attempt at secularizing the holiday. The Cranston man says Chafee's word choice is insulting to the state's Christians.
