Christie opened with a few positive remarks about Trump's strong leadership and voices that want Donald Trump being heard in the hall, then he went into this administration that refuses to prosecute Hillary or hold her responsible for her record as Secretary of State. So he will do that onstage.
Pundits are impressed with his prosecutorial style. He says straight up he intends to prosecute her and allow us to be jury. Then proceeds item by item beginning with North Africa and the overthrow of Qaddafi in Libya all across the globe, through the Middle East and China and Russia then Cuba and ending with the FBI.

Viewers liked his trained pit bull type meanness. Even his detractors are impressed. But that's it. Both of them compress the whole thing into that summation; Christie being prosecutor.
He left out a lot. He could have put the entire European migration debacle on her shoulders. He could have linked precipitous withdrawal from stabilized Iran to all that and place blame on her ideologic wavering leadership. He didn't even mention Egypt and Muslim Brotherhood. Didn't mention South China Sea. He could have enumerated her exposed lies through the decades that are important to people but he didn't. Obama's foreign policy history is her foreign policy history too. She has a lot of history he left out, so much that even talking about it is wearisome. So wearisome it drags down your own convention were you to be thorough about it, so all of it gets summed up as, "typical attack on Hillary that you expect."
