Barely a year after GLAAD named its new president, Herndon Graddick is resigning from his position with the LGBT media-watchdog group, Advocate.com reported. (Graddick’s resignation is effective immediately.)

Under Graddick’s leadership, GLAAD launched a highly visible campaign against the Boy Scouts of America’s ban on gay Scouts as well as gay and lesbian scoutmasters, and Graddick led the organization’s efforts to educate the mainstream media on how to report on transgender people. GLAAD’s chief of staff, Dave Montez, will serve as acting president, and the organization’s board of directors is scheduled to meet next month to determine its next steps.
