Decorah, Iowa (CNN) - It was a rare sight, but Callista Gingrich, wife of GOP hopeful Newt Gingrich, stepped in front of the microphone to introduce her "husband and best friend" at a pizzeria Tuesday.
As much as the former House speaker boasts of his wife's involvement in his campaign, she rarely speaks on the record or at campaign events. She is a familiar face on the campaign trail and at book signings, often standing next her husband at the podium, but she rarely takes center stage herself.
Callista Gingrich, who attended Luther College, chose to make the final stop in Tuesday's Iowa campaign swing in the college town to introduce her husband at Mabe's Pizza.
She shared some of her personal history with a packed room in the basement of the legendary pizza restaurant.
"One little known fact is that I actually lived upstairs above Mabe's Pizza as a senior, so Mabe's is very special to me," she said.
She quickly moved on to tout her husband's credentials.
"A lot of people ask me why Newt would be a good president, and I really think that Newt has been preparing for this challenge his entire life," she said in Decorah.
"He has a proven record of national leadership, a thorough understanding of our nation's history and a genuine love for our country, and I believe he is the best person to lead our country."
