going to take continued perjury and continued support of these individuals to perpetuate the cover-up and that i did not believe it was possible to so continue it. i told him that there was a cancer growing on the presidency and if the cancer was not removed the president himself would be killed by it. and he said that it would be handled properly. >> now it is on the public record, john dean's damning, if largely unsubstantiated, testimony that the president knowingly participated in the watergate cover-up. nothing less than richard nixon's presidency may ride on whether the public believes john dean or not. let's be honest, insurance can feel a little outdated. the paperwork... the calling for everything.
