Byrne said Clinton was feared by her staff and was notorious for her yelling. Byrne told Hannity that she has "blown up" at him and other Secret Service agents.
"She gets angry at things that are policy issues that, you know, take time to fix, and she's got this attitude where she wants things fixed right now, immediately. She screams and yells at people," Byrne said in an interview aired Monday night.
"There’s many examples that I site in my book where she blows up at people," Byrne said. "Like I’ve said, she has blown up at me before, and agents, and her staff. At one time, I saw her staff so afraid to tell her about a mistake that was made. They weren’t upset about the waste of the mistake, ordering the wrong invitations, they were terrified that someone was going to have to tell Hillary Clinton that there was a mistake made."
Byrne says Clinton's behavior during his tenure in the Secret Service proved to him that she does not have the temperament for the Oval office.
BYRNE: I feel so strongly that people need to know the real Hillary Clinton and how dangerous she is in her behavior. She is not a leader. She is not a leader.
SEAN: She does not have the temperament?
BYRNE: She doesn’t have the temperament. She didn’t have the temperament to handle the social office when she was First Lady, she does not have the temperament.
SEAN: She’s dishonest.
BYRNE: She’s dishonest, she habitually lies, anybody that can separate themselves from their politics and review her behavior over the past 15 years…
SEAN: You’re going to be accused of being political.
BYRNE: Absolutely I’m sure I will be, I have already and it’s not.
SEAN: And what’s your answer?
Byrne: It’s got nothing to do as politics.
Byrne talked wrote about then-President Bill Clinton's behavior, accusing him of carrying on multiple affairs and gave his perspective on the Monica Lewinsky affair and the scandal as it was happening. Byrne talked about several different affairs and how the Secret Service was expected to clean up after him.
HANNITY: How many women do you know, for sure, that he had affairs with in the Oval Office?
BYRNE: In the White House complex? I’d say easily three, maybe four, that I know of.
HANNITY: And you could see Monica Lewinsky from a mile away?
BYRNE: Sure. Sure.
HANNITY: You knew she wanted to be near him.
BYRNE: She was certainly manipulated some of the staff, other officers, myself to find out where he was—
HANNITY: She wasn’t manipulating if you saw through it.
BYRNE: Yeah, I agree. But I saw through it right away, but she was trying to place herself in his path, as he would move throughout the complex.
Byrne talks drug use in the White House:
HANNITY: Before I get into all the issues involving Bill and Hillary and what she knew and didn't know and covering up and lying and you being put in the middle of all this. People use drugs the at the White House?
BYRNE: There were some issues. One of the ones I comment in my book, and I'm very careful not to tell too much about it because I don't want -- hopefully this person got on with their lives and lived a healthy life. But there was one particular staff member that they had come in in the morning, and they'd be so beat up and exhausted looking, worn out, exhausted to the point where they couldn't be seen saying good morning. And they'd go in their office and go the bathroom and come out of the bathroom completely elevated and happy and smiling.
HANNITY: It was obvious you thought coke was being used?
BYRNE: I did. And later on, I was told that this particular person actually, they did something similar to an intervention and got her help and got her to a clinic, and I never did see her again. But I understand she did all right.
