(CNN) – Republican presidential candidate Tim Pawlenty said Sunday he remained uncertain over whether homosexuality is biological or a choice.
“As I understand the science, there’s no current conclusion that it’s genetic,” Pawlenty said Sunday on NBC’s “Meet the Press.”
Saying he preferred to “defer to the scientists” about the issue, the former Minnesota governor said it was unclear if being gay or lesbian was a lifestyle choice.
“There’s no scientific conclusion that it's genetic. We don't know that. So, we don't know to what extent it's behavioral,” Pawlenty said. “That's something that has been debated by scientists for a long time.”
He used the questioning as an opportunity to again describe his views opposing the legalization of gay marriage.
“I'm a supporter of traditional marriage between a man and a woman,” Pawlenty said. “I have not supported the issues of allowing gay couples to have the same benefits in public employment as traditional couples.”
