The FBI was warned at least twice about the maniac who killed 17 at a Florida school this week.
The latest warning was apparently just a month ago.
Yet agents did nothing to follow up on the warnings from concerned citizens.
Sen. Marco Rubio said Friday the FBI needs to be investigated for its chronic failures in this case.
Why just this case, Senator?
