The Human Rights Campaign (HRC), the nation's largest LGBT advocate, on Friday released a video congratulating Iowa on four years of gay marriage.

On April 3, 2009, the Iowa Supreme Court handed down its unanimous Varnum v. Brien decision which brought marriage equality to the Midwest and Iowa county recorders began processing marriage licenses for gay couples on April 27.

At least 360 couples, including 26 out-of-state couples, were granted marriage licenses on the law's first day.

The first to marry in Polk County were a lesbian couple. Shelley Wolfe, 38, and Melisa Keeton, 31, received a waiver from the customary three-day waiting period because Keeton was 25 weeks pregnant.

Approximately 6,000 gay and lesbian couples have tied the knot In Iowa.

“Iowa. America's heartland,” a male announces says in the 30-second video. “A place where for the past four years gay and lesbian couples can get married. Some thought it would the downfall of humanity. But the cows still get milked, the wheat and corn still grow high and puppy dogs are still cute.”

“Way to show 'em Hawkeyes. And happy anniversary.” (The video is embedded on this page. Visit our video library for more videos.)
