"It is my duty to state in a solemn declaration to History that I have never been insinuated with any movement or tendency to hurt the law or the institutions. I have always heard categorical statements from the President that he would be an uncompromising defender of legality and democratic institutions. [...] I could never defend a government committed to communism."
January 1, 1970
