Salt Lake City, USA - Mitt Romney said Saturday that criticism of his Mormon religion by rival Republican presidential campaigns is happening too frequently.
"Clearly, any derogatory comments about anyone's faith — those comments are troubling. The fact they keep on coming up is even more troubling," Romney said during a fundraising trip in the home state of The Church of Jesus Christ of Latter-day Saints.
The Mormon church is one of the fastest-growing religions and claims about 12.5 million members worldwide. But many evangelical Christians in crucial primary states such as Iowa and South Carolina consider the faith a cult.
The former Massachusetts government is trying to become the first Mormon elected to the U.S. presidency.
Romney's remarks follow an apology from Republican rival John McCain's campaign for comments about the Mormon church allegedly made this year by a volunteer.
Also recently, Republican presidential hopeful, Sen. Sam Brownback of Kansas, issued a similar apology for a campaign worker's e-mail to Iowa Republican leaders that was an apparent attempt to draw unfavorable scrutiny of Romney's religion.
Former New York City Mayor Rudy Giuliani apologized after the New York Sun noted that a campaign aide had forwarded to a blogger a story about unofficial Mormon lore. Legend has it that a Mormon would save the Constitution, the story said. The campaign aide passed the story along with a note: "Thought you'd find this interesting."
Romney said in a large presidential race there always will be some volunteers or workers who cannot be controlled. But he said the difference between derogatory comments that originated from the McCain campaign and others is that the Arizona senator has not personally apologized to him.
"In the case of Senator Brownback and Mayor Giuliani ... they called immediately. They each spoke with me personally. I don't have any issue with that at all," Romney said.
He said McCain "can do whatever he feels is the right thing. There's no need for me to suggest how people respond to things that go on in the campaign."
Tucker Bounds, a McCain campaign spokesman, said the McCain campaign has already apologized.
"It's a very sincere apology. There is absolutely no place for those type of comments in our campaign," he said.
Romney said he had not spoken with McCain since the last presidential debate, on June 5.
Romney was attending fundraisers in Salt Lake City and in Logan on Saturday.
