And so, the nation witnessed a tweet in which the president, a leader to whom the country once looked for healing in times of national tragedy, instead used innocent victims, high school children mowed down in their own school, to make his bogus, self-interested point: "Very sad that the FBI missed all of the many signals sent out by the Florida school shooter.
