GOFFSTOWN —Former U.S. Rep. Carol Shea-Porter has accepted an invitation from the New Hampshire Business and Industry Association to participate in a Sept. 17 candidates forum at the New Hampshire Institute of Politics at Saint Anselm College.

The association is sponsoring the forum with the New Hampshire Union Leader, New Hampshire Public Radio and New Hampshire Public Television. The Institute of Politics is at Saint Anselm College.

Shea-Porter is running against U.S. Rep. Frank Guinta, who defeated her in her reelection bid in 2010.

Her campaign said Saturday that she agreed to the forum following Guinta's acceptance to a debate at Temple Adath Yeshurun in Manchester. The bebate is hosted by the Manchester Chamber of Commerce.
