Secret Service Director Julia Pierson House should be ousted from her job, Minority Leader Nancy Pelosi said Wednesday, agreeing with the recommendation of the top Democrat on the oversight committee. Mrs. Pelosi, the highest-ranking woman in American politics, said problems go beyond Ms. Pierson, who was put in charge of the Secret Service after a scandal involving agents who hired prostitutes in Cartagena in 2012. But Mrs. Pelosi said she accepts the analysis of Rep Elijah Cummings, the ranking Democrat on the House oversight committee, who said he was displeased with Ms. Pierson’s leadership.
