California Lieutenant Governor Gavin Newsom will headline a gay rights fundraiser in Utah on Saturday.

The 43-year-old Newsom will speak at Equality Utah's 10th annual Allies Dinner at the Calvin L. Rampton Salt Palace Convention Center in Salt Lake City. Tickets are $100, and proceeds benefit Equality Utah, the state's largest gay rights group.

In 2003, then-San Francisco Mayor Newsom ordered city hall clerks to issue marriage licenses to gay and lesbian couples in violation of state law. Several thousand gay couples were married during the “winter of love,” but eventually the California Supreme Court ordered the city to stop and invalidated all the marriages.

The city, along with gay groups and individuals, sued the State of California. The court sided with Newsom, and in May of 2008 struck down the 2000 law that banned gay marriage.

Opponents of marriage equality fought back with Proposition 8, a constitutional amendment that when approved by voters in 2008 overturned the state Supreme Court's decision. Proposition 8 backers have appealed a federal district court ruling declaring the ban unconstitutional.

Newsom's commitment to gay marriage and the gay community never wavered.

“[I]f you believe fundamentally that people should have rights that are of the same sex, but you're not willing to extend them equal rights, then what is it about that point of view that distinguishes it from your point of view about civil rights for people based on race or ethnicity? What is inherently more significant about someone and their rights that happens to be of a different race that should not be extended equally to someone who may have a different sexual orientation?” Newsom said in 2008 while attending the Democratic National Convention.
