Hard to put out useful info on Trump when the Democrats already had the Steele Dossier, Russian pee tapes and other fake things out in the news cycle, to go along with the Access Hollywood tapes which were real and quite sensational as well. If you read about the info Wikileaks had on Trump it just wasn't sensational enough for anybody to care.
All the good stuff on Trump (along with some good dirt on down ballot Republicans and Democrats) was leaked through DC Leaks.
