Candace Gingrich-Jones, half sister of Newt Gingrich, has applauded his shift on gay marriage.

On Thursday, Gingrich, who earlier this year reiterated his support for a federal amendment defining marriage as a heterosexual union, told The Huffington Post that the Republican Party needs a reality check on the issue, adding that he personally was okay with civil, but not religious, marriage for gay and lesbian couples.

Writing at the Human Rights Campaign's (HRC) blog, Gingrich-Jones said, “Finally, something on which we can agree.”

“On a personal level, reading the interview made me proud of my brother,” she wrote. “The time my wife Rebecca and I have spent with Newt has had an effect and he has evolved on marriage. I know this was just one interview and I don't imagine he'll be Googling PFLAG anytime soon, but it is most definitely progress. And while the rest of America may not get the spotlight my family does, this same progress is happening everywhere. It is inspiring to know that the conversations we as LGBT people have with our families and loved ones, neighbors, co-workers and classmates, can lead to real change in hearts and minds. It's not an easy journey, and it sure ain't over, but I hope our family's experience can give a little hope to those who are on the same path.”

“Thanks for the early Solstice present, brother. I look forward to your and the GOP's continued evolution on issues of LGBT equality.”
