After a series of embarrassing incidents that called into question the efficacy of the Secret Service, Julia Pierson, the agency's director, has resigned.

Homeland Security Secretary Jeh Johnson said Pierson offered her resignation today and he accepted it.

"I salute her 30 years of distinguished service to the Secret Service and the Nation," Johnson said in a statement.

Johnson announced that Joseph Clancy, formerly the special agent in charge of the Presidential Protective Division of the Secret Service, will leave the private sector to serve as the agency's acting director.

As we've reported, the Secret Service came under scrutiny after a man scaled a fence, ran past guards into the White House where he allegedly managed to run through most of the building's main level.
