Pete Buttigieg was accused of “contradicting God’s word” by pastor Rhyan Glezman, the older brother of his husband Chasten.

Glezman spoke out after Buttigieg questioned how Christians could support Donald Trump.

“Well, I’m not going to tell other Christians how to be Christians, he said during a CNN town hall event on Tuesday, February 18.

“But I will say I cannot find any compatibility between the way this president conducts himself and anything that I find in Scripture.”

The Democrat’s brother-in-law said that it was the “the height of intellectual dishonesty for Pete to make claims that there’s no compatibility with being a Christian and voting for Trump”.

“Just everything that Pete is pushing is, it’s anti-God. I’m just gonna be honest with you,” he told Fox News’ Tucker Carlson Tonight.

He’s the one that is openly contradicting God’s word over and over.

Glezman has previously spoken out against the Buttigiegs, telling The Washington Post that “while he wants the best” for his brother, he doesn’t “support the gay lifestyle”.

The pastor was interviewed for a profile of Chasten, in which the would-be first gentleman said he had been forced to leave home after coming out because his brothers rejected him.

Glezman rejected this version of events, and accused the Buttigeigs of making up the story for political clout.

“A mayor from a small city and his husband, a child who grew up with nothing and his parents kicked him out … it makes a perfect political story for the campaign,” he told The Washington Examiner.

“To me that’s very sad. If that’s all you have to stand on, you’re not fit to be president of the United States.”

Pete Buttigieg goes into Nevada caucuses after trying week.

Buttigieg’s campaign for the Democratic presidential nomination will be tested on Saturday, February 22 at the Nevada caucuses.

The former South Bend, Indiana mayor has spent much of the week defending himself after right-wing commentator Rush Limbaugh questioned his suitability for the White House as a gay man.

Buttigieg fired barbs at both Limbaugh and Trump at the CNN town hall event, laughing at “the idea that the likes of Rush Limbaugh or Donald Trump [could be] lecturing anybody on family values”.

“One thing about my marriage is it’s never involved me having to send hush money to a porn star,” he added.
