SALT LAKE CITY (AP) – The head of a gay rights group on Feb. 11 said he plans to file a second campaign finance complaint about the Mormon church’s activities in the November ballot initiative that banned same-sex marriage in California.

Fred Karger, founder of Californians Against Hate, accused The Church of Jesus Christ of Latter-day Saints of deliberately covering up its financial role in backing Proposition 8 by failing to file timely campaign finance reports as required by California law. Karger said it’s possible the church spent millions more than it actually reported.

“I’m calling this Mormongate,” Karger said. “I think there’s been a massive cover-up.”

The church said it would have a response to Karger’s allegations later in the day.

Karger filed an initial complaint about the church with the California Fair Political Practices Commission in November. An investigation is under way.

A Jan. 30 report shows the church gave $189,903.58 in non-monetary contributions to the “Yes on 8” campaign.

The expenses included $97,000 for staff time and $21,000 for the use of church buildings and equipment. Most of the rest went for travel expenses, including airline tickets, hotels and meals.

The church reported no cash donations.

Church spokesperson Kim Farah has said the value of the church’s in-kind contributions is less than one-half of 1 percent of the $40.8 million raised by the campaign.

In response to the allegation that it tried to hide its support for Proposition 8, the church posted on its Web site a list of seven campaign finance reports dating back to last summer.

According to the church, all filings went to the California secretary of state; the Department of Elections for the City and County of San Francisco; and the registrar-recorder for Los Angeles.

Karger disputes the data and called on the public to share any pertinent information about the church’s activities related to Proposition 8. He said he’s set up a Web site and a toll-free telephone number to receive information.

Also last week, Karger called for a boycott of car dealerships in Utah, California, Iowa and Texas owned by the Utah-based Ken Garff Automotive Group. Katherine Garff made an individual contribution of $100,000 to the Yes on 8 campaign, Karger said.

Garff’s son, John Garff, said the contribution was a personal decision made by his mother, and not a contribution from the company, which is politically neutral.

John Garff said the company has gay and lesbian employees, has a zero-tolerance policy for harassment and discrimination in the workplace and offers a benefits package that is favorable to those in same-sex partnerships. In Utah, the automotive group is also a longtime contributor to the Human Rights Campaign, a gay rights advocacy and education organization.

Karger said he was unaware of the Garff company policies and welcomed an invitation from John Garff to meet and talk.
