comey's twitter handle. fbi? no, you set the bureau back by years. doj? no, broke every rule. usa? no, blew up a candidate. your oath? no, didn't quit. fired. only one thing, not subtlety on twitter. >> or off twitter. >> or off twitter, yes. what is your take on kind of the way comey has set himself out here from a political perspective? >> well, he's vulnerable with this book. he's clearly got both partisans on the democratic side and on the republican side who frankly hate his guts and think he made a lot of bad judgments in his time as the fbi director. in his book he has a few chapters detailing his work on the clinton e-mail investigation. he defends his handling of it. he says with a couple stylistic points about the speech in july he would have done differently. substantively he would not have done anything differently. what i found pretty striking is the message of sort of apology
