The original phrase Clinton appears to have changed is "people in glass houses shouldn't throw stones." Clinton inserted "covfefe" in reference to Trump's tweet that went viral just after midnight Wednesday.

"Despite the constant negative press covfefe," Trump tweeted.

Clinton's message jabbing at the president was a quote tweet of Trump, who earlier in the evening had hit Clinton for refusing "to say she was a terrible candidate."

"Crooked Hillary Clinton now blames everybody but herself, refuses to say she was a terrible candidate. Hits Facebook and even Dems and DNC," Trump wrote on Twitter.

Trump's attack came after Clinton criticized the Democratic National Committee's data operation earlier Wednesday during a Q&A session at Recode's Code Conference in Rancho Palos Verdes, Calif., saying that she "inherited nothing" from the party after she became its presidential nominee.

"I mean, it was bankrupt. It was on the verge of insolvency. Its data was mediocre to poor, nonexistent, wrong," she said. "I had to inject money into it."
