Indiana Governor Mike Pence gave the keynote address Wednesday night, formally accepting his party's nomination for vice president, but his speech was overshadowed by Texas Senator Ted Cruz's speech in which he refused to endorse Trump.
If it weren't hard enough to produce a blockbuster address for the most unpredictable Republican nominee in modern memory, Miller will need to shoulder the additional scrutiny foisted on the candidate after his campaign admitted on Wednesday that parts of the convention speech his wife delivered Monday were drawn from an earlier address given by Michelle Obama.
"Senator Cruz, yes or no - you will support Donald Trump if he is the nominee", asked moderate Bret Baier.
"I can tell you I am not voting for Hillary", said Cruz, who also said he was "watching" other candidates. And you know, he'll come and endorse over the next little while. he'll - because he has no choice.
And so I can understand why there's still some hesitation, but, again, it's a decision of conscience. "This is the legacy of Hillary Clinton: death, destruction, terrorism and weakness", Trump said.
Illegal immigrants, Trump said, "are being released by the tens of thousands into our communities", where he said they were straining resources, taking jobs away from American citizens and in some cases, committing crimes.
"Indeed, three days ago I talked on the phone with him and told him, 'I'm not going to endorse you, '" Cruz said. They gave me his speech.
Trump used his speech to lay out domestic threats and worldwide ones facing Americans, which he says he will be able to end.
"I am not in the habit of supporting people who attack my wife and attack my father", Cruz responded. "He doesn't speak for anyone who thinks our country should be standing together not splintering apart", Clinton said. As the speech went on the crowd became restless.
After Cruz left the stage, he and his family were confronted by angry RNC members, according to CNN.
A number of delegates said they appreciated how Trump steered clear of the kinds of attacks on fellow Republicans that characterized his primary campaign.
Coats stinging rebuke follows Cruz's prime-time convention speech last night.
Cruz said during his primetime speech that voters should, "Stand and speak and vote your conscience". "I think he's a lovely guy, a lovely guy". "Will I vote for Donald Trump?". But it's Trump. So it was an unmitigated mess of free association, punctuated with a prolonged rehashing of every beef with Ted Cruz he had in the primary, even down to reiterating his conspiracy theory about Cruz's father and JFK's assassination.
One political convention is down with one more to go.
The speech represents Trump's best chance yet to try to broaden his appeal.
