MONTREAT, N.C. — Republican presidential candidate Mitt Romney is visiting the Rev. Billy Graham at Graham's home in North Carolina.

Romney on Thursday went to see Graham and his son, Franklin, at the elderly evangelist's mountaintop home near Asheville while in the area for a campaign event. The 93-year-old Graham is in frail health.

Romney told the Grahams that, quote, "prayer is the most helpful thing you can do for me."

The Republican nominee has faced some difficulty making inroads with evangelical voters, in part because some believe his Mormon faith means he is not a Christian.

Romney also once supported abortion rights, and raised questions again this week when he told a newspaper he would not pursue abortion-related legislation as president. He later said he would be, quote, "a pro-life president."
