Fannie Mae’s board chairman and the mayor of Atlanta are in a heated dispute over roughly 100 acres of vacant land that the city said was supposed to serve the low-income population. In fact, Mayor Kasim Reed is suing Egbert Perry and has asked him to step down from his position as non-executive chairman of Fannie’s board. Perry, co-founder and CEO of the Integral Group, joined the GSE’s board in late 2008, and has been chair since 2014. He says he hasn’t done anything wrong. The argument stems from what the mayor calls a “secret deal” made with Integral in 2011 by Renee Glover, the former president and CEO of the Atlanta Housing Authority, who now serves on Fannie’s board.
