On Wednesday, Hillary Clinton spoke at the Code Conference about her 2016 presidential loss, blaming the Democratic National Committee and insinuating that the Russians had help from Americans to influence the outcome.

She described the DNC as “bankrupt” and on “the verge of insolvency,” saying that she “inherit[ed] nothing” and that the DNC’s “data was mediocre to poor.” What’s more, she said that the Russians’ campaign to spread “fake news” and leak emails were potentially “guided” by Americans.

Her comments ignited a Twitter war with Trump. “Crooked Hillary Clinton now blames everybody but herself, refuses to say she was a terrible candidate. Hits Facebook & even Dems & DNC,” Trump tweeted.

Clinton’s response brought into play his recent and infamous “covfefe” tweet, writing: “People in covfefe houses shouldn’t throw covfefe.”
