That guy has one of the most punchable faces of all time.

Allison [about Morejon]

There's one thing you should know going forward. When it comes to avenging harm done to our people, we never forget.

Elizabeth

Matt: Let's face it. A baby carriage ain't exactly a man magnet.
Daisy [laughing]: I hate you so much.
Matt: But you know what is? [imitates puppy whimpers]
Daisy: You're just playing on my fear of dying alone to make me get a that dog you actually want.
Matt: That doesn't mean I'm wrong.

Matt: You're single. You're lonely. What you need is a loyal, uncomplicated companion.
Daisy: I know you're not talking about you.
Matt: Again, ouch.

Allison: Wait, you actually want to break up with Piper? Wow, you're an even bigger idiot than I thought you were.
Jason: You're an idiot.
Henry: All right, let's play "Who's an idiot?" later.

Henry: There's never been a more important time for us to insist our son to treat women with respect.
Elizabeth: You are preaching to the choir. [checks the kids aren't around] But sticking your nose into teenage romance? That way lies madness.

Matt: And why does she sit instead of, you know, scratch or something?
Bomb Dog Trainer: What happens when you touch a bomb?

Peter: I believe that the sanctions on the Qasim regime is a mistake, morally and strategically, and I have to object in the strongest possible terms.
Elizabeth: I understand. But the president sets policy and we execute it.

Elizabeth [to Blake}: Henry and I are going to go eat peanut butter and jelly sandwiches in the freezing cold park. This is what passes as a date night these days.
Henry: Don't wait up for us.

Elizabeth: What about the rest of them? The eighteen children crowded around the gate to their school down the block from where the bomb went off? Their teachers? The four nuns on their way to work at the AIDS hospice? We don't, we don't have the time to say their names aloud too?
Matt: Of course we do, Ma'am.
Elizabeth: Damn right we do.

Finding your voice as a leader is never easy, but it's pretty much the whole gig.

Dalton

It's a little hard getting schooled on authenticity by a guy with a comb-over.

Dalton [to Russell]

Madam Secretary Season 4 Quotes

Ah, the familiar rustle of Capitalism at work.

Jason [seeing the shopping bags]

Elizabeth: I love Bed Bath & Beyond.
Allison: Yes, you do.
Elizabeth: Because they have everything, they have things you didn't even know you wanted. That's where the "Beyond" part kicks in.
