Former New York City Mayor Rudy Giuliani drew some of the loudest applause during the first night of the Republican National Convention, practically screaming his judgments about law enforcement, Hillary Clinton, Islamic terrorism and misinformation about Donald Trump.
Giuliani strayed from his prepared remarks more than a dozen times, typically veering into a crescendo and an applause line.
Defending police officers, he boomed that cops across America devote their lives to 'protecting us – black, white, Latino, of every race, every color, every creed, every sexual orientation.'
'When they come to save your life, they don't ask if you're black or white! They just come to save you!'
GOP delegates gathered in Cleveland's Quicken Loans Arena ate it up from 'America's mayor,' best known for steering New York through the aftermath of the 9/11 terror attacks in 2001.
MAKE AMERICA SCREAM AGAIN: Rudy Giuliani yelled and boomed and blared his applause lines Monday night at the Republican National Convention, drawing wild applause but overloading his microphone
'AMERICA'S MAYOR': Giuliani is best known for piloting New York City through the aftermath of 9/11
'It's time to make America one again. One America!' he said, mocking President Barack Obama for a now-famous campaign speech about racial unity.
'What happened to "There's no black America, there's no white America, there is just America"? What happened to it? Where did it go? How was it flown away?'
Each successive exclamation seemed louder than the last as he spent 15 minutes on stage making the case that Trump, who will be nominated for the White House later this week, is a generous, warm-hearted man who has been misjudged.
'Every time New York City suffered a tragedy, Donald Trump was there to help,' he said. 'He's not gonna like my telling you this, but he did it anonymously. When police officers were shot, when firefighters were hurt, when people were in trouble, he came forward and he helped, and he asked not to be mentioned.'
'Well, I am going to break my promise to him. I'm going to mention it! This is a man with a big heart who loves people! All people! From the top to the bottom! From the middle to the side!'
Giuliain's wild gesticulations included the visual equivalent of a typo, stretching his arm downward for the word 'top' and upward when he said 'bottom.'
But his transmission had not yet reached its top gear.

'I am telling you this because I am sick and tired of the defamation of Donald Trump by the media and by the Clinton campaign! I am sick and tired of it!' he howled as thousands rose to their feet.
'This is a good man! And America should be sick and tired of their vicious nasty campaign.'
Giuliani, at his most credible when talking about al Qaida and the ISIS terror army, risked running off the rails when he defined America's enemy as 'Islamic extremist terrorism.'
'For the purposes of the media, I did not say all of Islam. I did not say most of Islam. I said Islamic extremist terrorism!' he reiterated.
And then, finger pointed, he blared into the arena: 'You know who you are! And we're coming to get you!'
Shouts of 'Rudy! Rudy! Rudy!' shook the rafters.
Some of Giuliani's rhetorical high points were prescribed in his prepared remarks, like the bolded and underlined words that led him to shriek that America 'must commit ourselves to unconditional victory' against Middle Eastern jihadis.
Other moments were entirely ad-libbed.
CALM BEFORE THE STORM: Giuliani recited a portion of the Gettysburg Address during his afternoon rehearsal at the convention podium
'ARE WE CRAZY?' Giuliani railed against the Obama administration's unfreezing of $150 billion as part of its nuclear deal with Iran
On the Obama administration's landmark nuclear deal with Iran, he vented about 'billions of dollars' being sent 'back into a country that's the world's largest supporter of terrorism.'
'We are actually giving them the money to fund the terrorists who are killing us and our allies!' Giuliani yelled, going off script.
'We are giving them the money! Are we crazy?'
Another high-decibel moment was a brief hit on the Benghazi terror attacks – describing 'Hillary Clinton lying directly to the families of the people who were killed. Right! To! Their! Face!'
Even a protester who unfurled a 'REFUGEES WELCOME' banner couldn't slow him down.
'It means we're getting to them!' Giuliani bayed, before repeating himself twice.
'It means we're getting to them! It means we're getting to them!
Giuliani appeared on stage briefly during an afternoon rehearsal, leaving no hints at all of what would come later.
During his brief visit to the podium, he calmly recited half of Abraham Lincoln's famed Gettysburg Address.
