Story highlights The joint appearance was rescheduled in the wake of the Orlando terrorist attack

Clinton aides hope Obama will be able to reach out to voters who flocked to him in 2008 and 2012

San Francisco (CNN) Hillary Clinton and President Barack Obama will campaign together for the first time in 2016 when they meet in Charlotte, North Carolina, on Tuesday, Clinton's campaign said.

The joint appearance was first set for earlier in June in Wisconsin, but was rescheduled in the wake of the Orlando terrorist attack. Clinton aides hope the event, which comes weeks after Obama officially endorsed Clinton, will help unify the Democratic Party around the former secretary of state and preview the way the President will stump for Clinton before November's election.

"In Charlotte, President Obama and Hillary Clinton will discuss building on the progress we've made and their vision for an America that is stronger together," the Clinton campaign said in its announcement on Wednesday.

Clinton aides believe Obama will be able to reach out to voters who flocked to him in 2008 and 2012. He will travel to white suburbs in the Rust Belt and the Midwest and will campaign in African-American communities in North Carolina, Virginia and other swing states for the presumptive Democratic nominee, according to aides.
