Former senior White House adviser Omarosa Manigault Newman promises to keep whistleblowing. Manigault Newman appeared on MSNBC on Tuesday to claim that she witnessed "a lot of corruption that went on both in the campaign and in the White House." The former Apprentice contestant, who departed her White House role in January, has the GOP and President Trump on edge now that she is doing a media tour to promote her new tell-all book, suddenly vowing to "expose" the administration's hidden secrets and alleging that Trump is a proven racist and misogynist. Manigault Newman claimed Trump "absolutely" knew in advance that WikiLeaks would make public a trove of leaked emails from Hillary Clinton.
