MACON, Ga. — As Newt Gingrich campaigns through the state he used to represent in Congress, he continues to suggest President Barack Obama is more sympathetic to Islam than Christianity.

The former House speaker uses the recent fights over whether Catholic institutions should pay for contraception and increased violence in Afghanistan to suggest the president does not place a priority on American interests.

“President Obama is very quick to apologize for Islam while he attacks the Catholic Church,” Mr. Gingrich said here Thursday night. “You’ll notice he’s very sensitive about problems involving Islam, but he has a willingness…” Mr. Gingrich said before changing topics. “This is the most anti-religious administration in American history.”
