(CNN) – Republicans vying for their party's presidential nomination reacted Sunday to the death of CBS News correspondent Mike Wallace:
Former House Speaker Newt Gingrich:
"Callista and I join our friend Chris Wallace and his family in mourning the passing of his father, Mike Wallace. Mike was a giant in news reporting and analysis. His investigative reporting was legendary, and his participation in 60 Minutes helped created a lasting institution. Mike Wallace's life created a legacy young reporters will study for years to come. The Wallace family is in our prayers this Easter Sunday."
Former Massachusetts Gov. Mitt Romney:
"My experience with Mike Wallace - integrity, charm, character. A great one goes home."
