Emphasizing his focus on media, Bradley announced that he is selling his stake in the investor research firm he founded in 2008, Potomac Research Group. Bradley is passing PRG to Suzanne Clark, who has been serving as president of Atlantic Media’s National Journal for three years. Clark, who founded PRG with Bradley, will become the company’s CEO next month.

“Only the chance to grow my own company could influence me to leave my exceptional colleagues at Atlantic Media,” Clark said. “I am exceedingly grateful to David for providing this unique entrepreneurial opportunity.”

Justin Smith, previously the president of Atlantic Consumer Media overseeing The Atlantic and its related entities, will now be taking on Clark’s responsibilities as well as president of Atlantic Media. Explained the company:

“Smith will now add to his responsibilities oversight of the National Journal and Government Executive Groups — including the industry-leading National Journal, CongressDaily, The Hotline and Government Executive publications.”
