The issue bubbled up in Washington, D.C., at the Values Voter Summit, where Perry was speaking to a packed house of evangelical Christians.
In an interview with reporters (see the video here), Jeffress said he believes Mormonism is a cult and that Romney won't energize evangelical voters.
Perry campaign spokesman Mark Miner told reporters that the governor doesn't believe Mormonism is a cult.
Mormon leaders commented on the controversy, telling ABC News: "We really don't want to comment on a statement made at a political event but those who want to understand the centrality of Christ to our faith can learn more about us and what we believe by going to mormon.org."
