Trump is now using a national tragedy and utter failure in addressing policy, to trash the investigation into Russia.  He’s claiming that because the FBI was busy investigating Russia, they somehow missed out on preventing the school shooting in Florida.  Beyond being an utterly disgusting way to shift the conversation away from his own misdeeds, it thoroughly, willfully disregards a lot of things, namely that the ENTIRE of the FBI, including the FBI agents in Florida, were focused on the Russia investigation, as opposed to a relatively small team lead by Robert Mueller.
