 The Homeland Security Inspector General will hold an investigation into the Secret Service response. And the head of the Secret Service, Kimberly Cheadle, will appear before a congressional committee on Monday.

You know, yesterday morning, Tuesday morning, when she went before the press and she said, you know, in an interview that she knows that the buck stops with her.
