John Dean: Trump Worst than Nixon

John Dean tonight on CNN:

"The nature of Trump's actions, the nature of his obstruction, is so much more venal than Richard Nixon's.  Someday, when I catch my breath, I'm going to sit down and make the comparison.  Trump makes Nixon look good, Trump's in a league of his own. . . "  

Is there a cancer within the Presidency:  "I think there is. . . .   We now have a President in his 800th day and it's very grim, it's not a healthy presidency, i'm not sure we can wait to 2020, this man could do great damage...  The senate will not do anything, until the makeup changes it's not very likely.  The house should start hearings for 2020 to show the public what's happening." . .
