The main group lobbying against passage of a gay marriage law in Minnesota has suggested that lawmakers were influenced by money.

Minnesota for Marriage on Friday said that it spent $200,000 fighting against the law's passage.

That's about one tenth the amount of money raised and spent during the same period by Minnesotans United for All Families, the group backing the law change.

“It's not surprising that they had to spend ten times more than traditional marriage supporters to convince legislators to redefine marriage and ignore their real First Amendment religious liberty concerns,” John Helmberger, chairman of Minnesota for Marriage, said in a statement. “It's proof that if you spend enough money you can get some legislators to do almost anything – even vote against the overwhelming wishes and interest of their constituents.”

Last month, Minnesota became the 12th state to legalize gay nuptials. The law takes effect August 1.
