GREENSBORO, N.C. -- President Obama always seemed very comfortable on the campaign trail; during his first two runs for the White House, he had a way of winning over voters, and now, he is trying to do that for Hillary Clinton.

Tuesday night, Obama took off his jacket, rolled up his sleeves and energized the crowd in Greensboro.

"I think I need to take off my jacket-- we got some work to do."

President Obama can still move a crowd. As the first democrat to win North Carolina in decades, he is campaigning hard to help Hillary do the same.

The president didn't hold back when it came to her opponent, taking several jabs at Donald Trump.

"This guy says stuff that no one finds tolerable," He said. "A guy who spent 70 years on this earth with no regard to working people, suddenly starts showing regard to working people."

A few protestors interrupted the president and they were escorted out, but Obama stayed on message.

Stephanie Watson says, "Obama had to let the people know we're not going to vote for some clown, somebody who disrespects women, somebody who cozies up to our enemies."

The president closed with a reminder to voters just how much is at stake November 8.

"Send a message for progress."

We're just four weeks away from election day.

Tim Kaine is in Charlotte Wednesday, and Donald Trump is in town on Friday.
