The Secret Service says an unarmed man jumped the fence on the north lawn of the White House just before 7 p.m. and made it to the North Portico doors before being nabbed. Secret Service Director Julia Pierson, in her first testimony on the breach, tells Congress that such an intrusion won't happen again but faces blistering criticism from dissatisfied lawmakers. In her testimony, she reveals that two of her uniformed officers recognized Gonzalez just before he jumped the fence from an earlier troubling encounter with him, but they never approached him that day or reported his presence to superiors. [...] Obama "concluded new leadership of that agency was required," said spokesman Josh Earnest.
