In the wake of a bombshell story about Russia’s meddling in the 2016 U.S. presidential election — and persistent allegations that President Trump’s campaign may have colluded with Russia to win — Trump took to Twitter Sunday morning to accuse someone else of collusion: his Democratic rival, Hillary Clinton.

Clinton, he charged, had colluded with the Democratic Party to defeat Sen. Bernie Sanders (I-Vt.) in the Democratic primary race.

“Is she allowed to collude? Unfair to Bernie!” Trump tweeted, seemingly defending the senator just characters after calling him “Crazy Bernie Sanders.”

The initial responses to the early morning tweet ranged from baffled to indignant. There was a difference, several Twitter users pointed out, between working with one’s own political party and “working with a foreign enemy.”

On Friday and Saturday, Trump turned to Twitter to lash out at Obama administration officials for not taking stronger actions against Russian election meddling — despite for months disputing that such meddling had occurred. He seemed to suggest, without offering proof or explanation, that the Obama administration had withheld action to help Clinton.

“Focus on them, not T!” Trump tweeted Saturday, presumably referring to himself.
