Hillary Clinton campaigns in Raleigh with Bernie Sanders, Pharrell Williams

RALEIGH, N.C. -- In a last push to win over voters in the battleground state of North Carolina, Hillary Clinton brought Senator Bernie Sanders and Grammy-winning artist Pharrell Williams to a rally Thursday.

"I'm not here to defend Hillary, she's a big girl, she can do that all by herself," Pharrell said to a crowd of more than 5,000 people. Pharrell told voters that he normally does not get involved in politics, but this election, he said, is different.

The message from Clinton and Sanders was that they are united and they want to continue the unity and prosperity that President Obama has worked to achieve. They also sharply contrasted their stances on issues like the economy, climate change, immigration and health care to those of Republican nominee Donald Trump.

"I think it's fair to say things are going to change, change is part of life that much is certain. The question is what kind of change are we going to see? Are we going to build a stronger, fairer, better America or are we going to fear each other and fear our future?" Clinton said.
