Mehmet Oz, the Republican nominee for the Pennsylvania Senate seat who says he is in favour of same-sex marriage, hosted a campaign event on Wednesday at a venue that bans same-sex marriages.

Oz, who has campaigned on supporting legislation that would enshrine same-sex marriage in federal law, held a campaign event at the Stone Gables Estate, a venue that only holds weddings between a man and a woman, reported the Washington Post.

“We provide marriage-related services as ordained by God’s Word, the Holy Bible, that are consistent with the written truth that marriage is the union of one man and one woman,” the venue says on its website.

In July, Oz announced that he would support legislation that would codify same-sex marriage into federal law should he be elected, reported the Hill.

Oz also tweeted in September about his support of gay marriage: “I’m proud to join this effort with fellow Republicans. I believe that same-sex couples should have the same freedom to get married as straight couples.”

But Oz has been accused of making other anti-LGBTQ comments during his campaign specifically targeted at the transgender community. He also removed an episode of his former television show, The Dr Oz Show, about conversion therapy from the show’s website, as well as a blogpost where he said he supported the medical consensus that conversion therapy was ineffective and harmful, reported the Independent.
