Reporter this report, the latest in a string of what appeared to be missed warning signs.

And in september, a youtube blogger alerted the fbi to a user with the name nikolas cruz, who posted on the channel, im going to be a professional school shooter. The fbi investigated, but turned up nothing. And over the past few years, the sheriff says they responded to 20 calls regarding cruz. All of this concerning for the victims and their families, like debbie hixon, who lost her husband christopher in the shooting. The system is broken and it needs to be fixed. Adrienne bankert joining us now. You just said officers visited cruz 20 times and state agencies were aware of serious mental issues. And none of that was flagged by the background check when he bought the ar15. Thats right, tom. Theyre only run if they were deemed mentally ill by the courts or admitted to a mental institution.

Campaign in 2014, long before i announced that i would run for president. The results of the election were not impacted. The Trump Campaign did nothing wrong no collusion a white house spokesman going a step further. There are two groups that have created chaos more than the russians, and thats the democrats and the mainstream media.

The defendants allegedly conducted what they called Information Warfare against the united states. Reporter and now, a superpower war of words. As you can see, with the fbi indictment, the evidence is now really incontrovertible. Reporter President Trumps National Security adviser at a security conference in germany, the russians in the same room, fighting back. Their foreign minister saying, until we see the facts Everything Else is just blabber. While this latest indictment does not mention collusion between the russians and the Trump Campaign, its just one piece of the broader mueller investigation. The probe is also looking into the 2016 trump tower meeting between donald trump jr. , jared kushner, paul manafort, and a russian lawyer, and theres a possible obstruction of justice investigation. Just because this indictment has no mention of collusion, or of knowing participation by americans, doesnt mean it isnt going to happen in the next indictment. All right, lets get out to kenneth moton, joining us from West Palm Beach with the president tonight. Sending out more tweets pointing to how long the accusations russia meddling go back. The president focused on when the alleged meddling started in 2014, long before he announced his candidacy.
