Andrea Mitchell is no stranger to Philadelphia. NBC News' Chief Foreign Affairs Correspondent and host of MSNBC's Andrea Mitchell Reports is not only a University of Pennsylvania alum who got her start at KYW, but she's a Penn trustee and travels back to the city regularly to attend board meetings.

Mitchell has been covering Democratic presidential nominee Hillary Clinton since 1992, and has been traveling with her for a year. Alas, neither Mitchell nor Clinton will get to sleep in their own beds post-Democratic National Convention. Instead, they'll both head out on a bus tour with Democratic vice presidential nominee Tim Kaine, which reminded Mitchell of a similar bus trip between former President Bill Clinton and Vice President Al Gore. "It was just magic in terms of political chemistry," Mitchell said, referring to Clinton-Gore, "and they're trying to recreate that tomorrow."

How has Philadelphia changed for you?

Philadelphia is so dramatically different. Not just the downtown and the vitality, and the new construction, new civic leadership. It's always been diverse, but it's much less separated. I'm an outsider now, but I think there's been such an improvement in political engagement and civil society.

You've been following Clinton for a long time.

I've been on the road with Hillary Clinton for more than year. I've seen such an evolution, I started covering her in 1992. It was during the January-February period of the caucuses. The scandals were hitting. She was being stalked. I asked her the question before the Illinois caucus about allegations of conflict of interest with her private law practice in Arkansas. It was at the Busy Bee in Chicago. And she famously said, "I suppose I could have stayed home and baked cookies and had teas." She was defensive. The protective shield she's grown around her grew out of that campaign. The controversies when they got into office -- Whitewater, a special prosecutor and her warnings against it -- She's been so hounded by the press, by Republicans. She called it the Great Right Wing Conspiracy. That is the context of why she wanted to keep her emails private. It was really bad mistake. 

She's always been in the smartest one in the class, she always did more homework. I was with her in Beijing and no on wanted her to say something as controversial about women's rights, that women's right are humans rights. It was a big deal, the Chinese were furious but it was absolutely inspirational to young women who wanted to get into politics.

Everything came to together last night. [Presidential historian] Michael Beschloss said:

When you consider how bitter their 2008 campaign was, it's amazing that Michelle Obama gave her the loving embrace she did.

But tonight is Hillary's big night.

I would not want to be in her shoes tonight. She's given some good speeches, like after clinched the nomination. But there's been so many bad pieces of luck. We were in Scranton and she was going to be endorsed by Joe Biden and those are the pieces she needs, and the tragedy of Dallas happened. She was going to be endorsed by the president, and the FBI director came out with his devastating report. She's not had an easy time. Now she has to follow Barack Obama giving the best speech of his life. But I think the affection was really genuine.

Everyone I've talked has said these conventions are not like anything they've seen before. What are the ramifications of that in the media?

The biggest change is social media. Donald Trump changed coverage because he made news yesterday. The lead story wasn't Barack Obama, it was Donald Trump suggesting our adversary Russia should conduct cyber war against us. She's had to deal with Trump dominating the airwaves and the news cycle and being able to spend no money on advertising by challenging Clinton through Twitter. There's that, and the 24-hour news cycle but that just means we get less sleep than we did before.
