Authorities barred pedestrians from the front of the White House for a few minutes Saturday after a woman tossed something over the fence.

The sidewalk along Pennsylvania Avenue just outside the fence was shut down “just long enough” to see what the object was, said Secret Service spokeswoman Nicole Mainor.

It turned out to be an apple core, Mainor said.

The woman who flung the core was questioned and sent on her way, according to Mainor.

Still unclear late Saturday night was why the woman threw the apple core.
