Conservative talk show host Rush Limbaugh asked aloud on his radio program Thursday why President Barack Obama made the choice to become a Christian.

Limbaugh, referencing the president’s recent trip to a Baltimore mosque this week, argued Obama is “constantly talking [Islam] up.”

“President Obama is routinely defending it, talking it up, promoting it,” Limbaugh contended, according to an online transcript posted to his official website.

“He talks about how awesome Islam is all the time, one of the most beautiful sounds he’s ever heard is the morning call to prayer in an Islamic country,” the radio show host added. “He says it’s the most peaceful, most giving religion out there, that the mosque called a prayer one of the most beautiful sounds in the world. And, at the same time, he’s out there, and look what he says about Christians. He says he is one. Look, he talks about ‘em as bitter clingers and they hold on to their guns when they’re nervous.”

Limbaugh then revealed his question.

“My question is, given all this, why did he choose to become a Christian? I’ve always wondered that,” he told his audience. “He’s such a defender and promoter of Islam, and, on the other hand, he and his party are constantly denigrating Christians. I don’t care what the issue is, whether it’s guns, whether it’s gay marriage, any cultural or social issue, or the bitter clinger comments. I’ve always wondered about this.”

The radio host argued he was “not saying anything.”

“I’m just asking a question,” he insisted.

Limbaugh’s question hit on a tone many on the right have advanced in the last seven years. Throughout the Obama presidency, certain right-wing websites and media outlets have suggested — and outright claimed — that the president is a secret Muslim. Such claims have been dismissed by Obama who has used them as the punchline for jokes.
