Candace Gingrich, the self-described “lesbian genderqueer” half sister of former House Speaker Newt Gingrich, has described Republicans as unwilling to evolve on LGBT rights.

While Donald Trump, the presumptive Republican nominee for the White House, picked Indiana Governor Mike Pence as his running mate, Newt Gingrich was considered a top three contender for the position along with New Jersey Governor Chris Christie.

Candace Gingrich, who runs an internship program at the Human Rights Campaign (HRC), told gay glossy Out that none of “those three were going to soften [Trump's] stance” on LGBT rights.

She called it “unconscionable” and “disgusting” that House Republicans held a hearing on a bill that seeks to defend opponents of marriage equality on the one-month anniversary of a mass shooting at a gay nightclub in Orlando where 49 people died.

Gingrich agreed with the interviewer that Republicans appear “shockingly out of step with the culture.”

“Yeah, looking at public opinion, the rise of support for marriage equality, workplace discrimination protection, and hate crimes laws. … It's sticking their heads in the sand and not wanting to evolve. For a long time, their bread and butter has been anti LGBTQ rhetoric and legislation, and they're not willing to give up on that, no matter what century we happen to be in,” she said.
