Suspicious Dump Truck Found Near White House

ABC News reports:

All car and pedestrian traffic has been stopped for several blocks in a perimeter around the White House this morning as law enforcement inspects a dump truck there.

The Secret Service tells ABC News that a canine team “alerted” while inspecting a dump truck that was scheduled to come into the construction complex on the White House's North Lawn.

There has been a steady stream of dozens of heavy construction vehicles and scores of work crews at the White House working on a two-year project that has torn up the North Lawn of the complex.  

The truck which raised concerns was on a manifest of vehicles cleared into the White House for scheduled work.  Like all vehicles,  it is screened at a distant access point before being allowed anywhere near the White House itself.
