SANTA FE, N.M. (AP) — Republican and Democratic candidates for governor in New Mexico have agreed to participate in a public forum Sunday about the public's right to access government documents and other transparency issues.

New Mexico Foundation for Open Government Executive Director Peter St. Cyr said the participation of all gubernatorial candidates is a testament to widespread concerns about transparency in government as an essential component of democracy.

A live webcast of the forum in Albuquerque is planned on the foundation's Facebook page .

Republican Gov. Susana Martinez cannot seek a third term in November elections. U.S. Rep. Steve Pearce is the only Republican candidate for the top statewide office. The Democratic nomination is being sought by U.S. Rep. Michelle Lujan Grisham, state Sen. Joseph Cervantes, former media executive Jeff Apodaca and educator Peter DeBenedittis.
