The Knights of Columbus, a Catholic charitable organization, has given $100,000 to Protect Marriage Maine, the group leading efforts to oppose same-sex marriage in Maine.

The money comes from the international offices of the group, according to a press release.

"I believe this gift will encourage many other Mainers to financially support our efforts to protect marriage as the union of one man and one woman," said Bob Emrich, chairman of Protect Marriage Maine. "We look forward to continued financial and grassroots support as the campaign gears up for its final phase of advertising and get-out-the-vote efforts prior to Nov. 6."
