Jem Aswad Senior Music EditorAtlanta rap trio Migos on Wednesday filed a complaint against their longtime attorney Damien Granderson, claiming that he “abused his position of trust as Migos’ fiduciary from the moment he was retained as Migos’ lawyer” and “cheated [the group] out of millions of dollars,” accusing him of “glaring conflicts of interest” and favoring the group’s label, Quality Control, which he also represented.
