Raleigh, N.C. — First lady Michelle Obama will make a campaign stop in the Triangle next week, the Obama campaign said Thursday.

Michelle Obama will participate in a "grassroots event" in Chapel Hill on Tuesday to drum up support for her husband's re-election bid. The visit comes two days before early voting begins in North Carolina.

North Carolina-based band Delta Rae will perform at the event, which is free and open to the public. Tickets are required due to limited space and will be available at 10 a.m. Saturday on a first-come, first-served basis at Obama campaign offices in Raleigh, Durham and Chapel Hill and at The Pit on the University of North Carolina at Chapel Hill campus.

Last month, the first lady visited North Carolina Central University in Durham to build support among college students. In August, she made a campaign stop in Greensboro.

North Carolina is one of handful of battleground states where the Obama and Republican opponent Mitt Romney are spending time and resources and lots of money on advertising. Obama narrowly won North Carolina's electoral votes four years ago.
