Rep. Louie Gohmert (R-TX) on Tuesday said that judges who have struck down state bans on same-sex marriage, like those in Utah and Oklahoma, need "basic plumbing lessons." 

Gohmert said that these judges are denying the biological reasons for restricting marriage to between a man and a woman. 

"'Basically, we haven't seen any biological evidence to support marriage being between a man and a woman,'" he said, summarizing the judges' rulings during a Heritage Foundation event, according to Roll Call. 

And so the Texas representative said that the judges "need some basic plumbing lessons."
