CHARLOTTE, N.C. (AP) – President Barack Obama and presumptive Democratic presidential nominee Hillary Clinton are traveling to North Carolina to campaign together next week.

The Clinton campaign announced Wednesday that the two will appear together next Tuesday in Charlotte. No other details about the rally were immediately released.

North Carolina has been a key swing state. Obama won the state’s 15 electoral votes in 2008, but lost the state in 2012.

The event brings the two main rivals for the 2008 Democratic nomination for president together at the city that hosted the 2012 Democratic National Convention.

Clinton and Obama quickly reconciled their differences from the campaign trail, and Clinton served as Obama’s Secretary of State from 2009 to 2013.
