Welcome to Meet the Press Now, I'm Kristen Welker in Washington at a pivotal moment in the

Republican presidential primary.

There are contests in four states and the District of Columbia this weekend and this

Tuesday will be the single biggest night of the primary

with a whopping 865 Republican delegates at stake from coast to coast on

Super Tuesday. It could very well be the last chance for

Nicky Haley and Trump's skeptics in her party

to make their voices heard.

Amid that urgency, I sat down with Haley

on this set earlier today in an exclusive interview for Sundays meet the press.

Here's some of what she told me.

Do you think Donald Trump would follow the Constitution if you were elected to a second term?

I don't know. I don't know. I mean, you always want to think someone will, but I don't know.

You know, when you go in and you talk about revenge, when you go and you talk about, you know,

vindication, when you go and you talk about what does that mean mean like I don't know what that means and only he can answer for that what I can answer for is I don't think there should ever be a president that's above the law

I don't think that there should ever be a president that has

total immunity to do whatever they want to do. I think that we need to have someone

that our kids can look up to, that they can be proud of of and I think we need to have a country of

law and order a country of freedom and a country that goes back to respecting the

value of a taxpayer dollar and we don't have any of that right now.

Folks that's a pretty significant statement from someone who served in Donald

Trump's cabinet and a grave warning about a second Trump term.
