Mitt Romney’s son and senior campaign advisor, Tagg, said the press should find out who is behind the anti-Mormon calls that were made in Iowa and New Hampshire in a phone interview Monday morning.

When asked if the Romney campaign would make a push to find out who made the calls Tagg said: “We’re going to let the press do that. If there was something we could do, we would. The Attorney General in New Hampshire is going to look into it, so we’re going to let them pursue it.”

“We’d be happy to give any help people thought we could give, but I’m not sure there’s anything we know that would be of any use,” he said.

Last Thursday, media reported that voters in Iowa and New Hampshire were receiving calls that inflamed anti-Mormon sentiments.

Romney immediately issued a video response and said the calls were “un-American” and distasteful at “a time when we’re preparing for Thanksgiving.”

But, some people, like Erik Erikson of RedState.com and Washington Post editorial writers venture that a Romney supporter was making the calls and engaging in “push polling” to test how opposed voters were to Mormonism.

When the National Review echoed similar sentiments, Romney’s national spokesman Kevin Madden issued a combative statement: “Let me be perfectly clear: our campaign was not and is not involved with any efforts to engage in alleged push polling calls against our own candidate. The insinuation made by the National Review post is highly misleading.”
