The threat that prompted Los Angeles Unified School District officials to close all schools appears to be a hoax, congressman Adam Schiff, a member of the House Intelligence Committee, said on Tuesday afternoon.
"The preliminary assessment is that it was a hoax or something designed to disrupt school districts in large cities. The investigation is ongoing as to where the threat originated from and who was responsible," Schiff (D-Burbank) said in a statement quoted by the LA Times.
