President Donald Trump has long been obsessed with the idea that the investigation into Russia's attempted meddling in the 2016 election is really nothing more than a political scheme to rob him of the credit he so rightly deserves for winning that race. Over the last 24 hours, however, that obsession has been tuned up a notch, with Trump unleashing a series of bitter tweets attacking even his own top advisers and agencies for their alleged complicity in this narrative.

The news that a federal grand jury has indicted 13 Russians over interference in the 2016 US election comes on the heels of what would seem to be a totally unrelated event -- the mass shooting in a Florida school.
