George Stephanopoulos: What You Need to Know About RNC Day 1

These three key questions are on everyone’s mind as the RNC kicks off today.

“Well, I may speak up. To be honest, I want to see this,” he said when asked if he would be addressing the convention with his wife. “I'd love to be there when my wife speaks. So the answer is, yes, I will be there.”

The rumor in Cleveland is that he will introduce her.

Trump’s campaign chairman, Paul Manafort, confirmed that Melania Trump will address the convention on its first night.

Sources tell ABC that the former model and Trump’s third wife spent the weekend preparing for the address in New Jersey. The campaign has released no information about the focus of her speech or its length but did not rule out the chance that the presumptive nominee would make an earlier-than-normal appearance at the convention in order to introduce her.

Will Cleveland See Convention Unrest?

So far, there have been largely peaceful demonstrations in Cleveland. But the Ohio city is bracing for the worst, as recent domestic and international events have heightened security concerns.

“This city is prepared for that, but it’s also a city on edge,” Stephanopoulos said.

Thousands of law enforcement officers were ordered to Ohio even before the fatal shootings of police officers in Baton Rouge, Louisiana. More than 3.5 miles of security fences line downtown Cleveland, and a 5,500 officers, many from out of state, have been assigned to convention security.

After yet another tragedy, the head of Cleveland's largest police union called for an emergency action to suspend the state’s open carry laws during the convention. Ohio Gov. John Kasich said he does “not have the power to arbitrarily suspend federal and state constitutional rights or state laws as suggested.”

Cleveland Police Chief Calvin Williams said officers are “prepared for anything and everything” that could happen.

What About Unrest Inside the Convention?

Priebus said that never-Trump delegates need to recognize that GOP voters have made their choice. “They don’t like the idea that 14 million people ... picked someone that they didn’t want,” he said. “It’s a binary choice. It’s either Donald Trump or Hillary Clinton.”
