The Atlanta school board Ethics Commission decided Monday not to open an investigation into a complaint against Board of Education Chairman Reuben McDaniel.

The commission’s chairwoman, Rebecca Pentz, said the commission lacked facts to support claims that McDaniel received an improper benefit, and the ethics complaint was filed too long after the alleged violations occurred.

The complaint filed by parent Molly Read Woo, who supported McDaniel’s opponent Cynthia Briscoe Brown in this year’s school board election, questioned whether the school board hired a marketing agency to promote controversial policies, violated state law by privately discussing budget issues, or compromised the superintendent search process by including an associate of Mayor Kasim Reed in executive sessions.
