For the Second Time in three days the White House was put under a lockdown today.

White House officials say two people are in custody after throwing unknown items over the fence in multiple places.

President Obama is in California with members of his top staff.

The lockdown has since been lifted.

On Tuesday a driver entered the White House Perimeter after allegedly mistakenly joining the Whit House motorcade.

He was arrested and charged with unlawful entry.
