NBC Nightly News anchor Lester Holt interviews presumptive Democratic nominee Hillary Clinton following Tuesday's primaries.
LESTER HOLT, NBC NEWS: Well, let's talk about Donald Trump. One by one he picked off all the Republican challengers. What did you learn from his primary race as you go forward and face in him one-on-one?
FMR. SECRETARY OF STATE HILLARY CLINTON: Well, I think that there are several lessons from his primary race. Number one-- a lot of his primary opponents never took him on over issues, because they were somewhat close to what he was saying. And when it came to the personal attacks, because they didn't have any strong issue position to contrast with him they really couldn't come back on the personal side either.
HOLT: Is this going to be the nastiest campaign ever? Will you respond-- insult to insult?
CLINTON: No. Absolutely not. He can run a campaign of insults. I'm running a campaign of issues that are going to produce results for the American people. I'm going to talk about why he's unqualified to be president based on his own words and his deeds. And I'm going to continue to make the case he is temperamentally unfit to be Commander-in-Chief.
