President Barack Obama and first lady Michelle Obama are sending their thoughts and prayers to the victims of a stabbing spree at a Pennsylvania high school.
That's from White House spokesman Jay Carney.
Obama is in Texas on Wednesday for a memorial service for last week's shooting at Fort Hood. Carney said on the way to Texas that Obama was briefed by his staff about the Pennsylvania school attacks.
