From CNN: The reason McMaster might be out is that he said that Russia meddled in our Elections
..... and that meddling did not effect the outcome of the elections as per Trump.

Tension with Trump
Tensions between Trump and McMaster have been playing out for months and were on full display this weekend after Trump publicly chided him over remarks he made regarding Russian interference in the election.
"General McMaster forgot to say that the results of the 2016 election were not impacted or changed by the Russians and that the only Collusion was between Russia and Crooked H, the DNC and the Dems," Trump tweeted. "Remember the Dirty Dossier, Uranium, Speeches, Emails and the Podesta Company!"

Our democracy is in serious danger.
President Donald Trump is either totally compromised by the Russians or is a towering fool, or both, but either way he has shown himself unwilling or unable to defend America against a Russian campaign to divide and undermine our democracy.
That is, either Mr. Trumps real estate empire has taken large amounts of money from shady oligarchs linked to the Kremlin so much that they literally own him; or rumors are true that he engaged in sexual misbehavior while in Moscow running the Miss Universe contest, which Russian intelligence has on tape and he doesnt want released; or Mr. Trump actually believes Russian President Vladimir Putin when he says he is innocent of intervening in our elections over the explicit findings of his personally chosen chiefs of the CIA, NSA and FBI.
In sum, Mr. Trump is either hiding something highly threatening to himself or hes criminally incompetent to be commander in chief. It seems very likely that one of these scenarios explains Mr. Trumps refusal to respond to Russias direct attack on our system a quiescence unprecedented for any president in history. Russia is acting in a hostile manner, and Mr. Trump keeps ignoring it.
