Billy Graham's Throat-slashing comment to Nixon

A recently released audio tape by the Nixon Presidential Library shows a comment from Billy Graham in 1973 to then President Richard Nixon that has gotten a reaction from the Billy Graham Evangelistic Association. The exchange concerned the CBS television network coverage of Nixon’s first speech about Watergate.

Nixon: “What did CBS do? Did they knock it?”
Graham: “I felt like slashing their throats, but anyway God be with you.”

You can hear the exert on the audio file below. The tape was part of 340 hours of conversations released and posted online by the National Archives and Records. Graham's organization says:

Mr. Graham has always been the first to admit that he is a sinner saved by grace. In response to some of the things he said during the Watergate era, he admitted, “I sometimes put my foot in my mouth. I’ve made many statements I wish I could recall. I am an erring, fallible disciple of our Lord Jesus Christ, and am subject to all the temptations, human frailties and errors of other disciples of the Lord.”
