Robert McDowell announced yesterday that he would be leaving the five-member commission and now it appears the other shoe is about to drop. Republican McDowell’s announcement was widely believed to be a precursor to an announcement that Chairman Julius Genachowski also would be stepping down and now The Wall St. Journal, citing an FCC and industry official, reports that Genachowski is set to announce tomorrow that he is exiting as well. Genachowski’s office declined to comment. Genachowski’s departure would still leave the Democrats retaining the majority with two seats (Mignon Clyburn and Jessica Rosenworcel). Genachowski was appointed to the commission in 2009 by President Barack Obama. Both replacements require Senate confirmation.
