These two really don't like each other.

Hillary Clinton and Donald Trump are trading insults again on Twitter, after she blamed her election loss on the President's collusion with Russia, fake news, and Facebook during a recent sit-down at the Code conference.

"Crooked Hillary Clinton now blames everybody but herself, refuses to say she was a terrible candidate. Hits Facebook & even Dems & DNC," the POTUS wrote on social media.

Ol' Hill couldn't resist getting in on the "covfefe" typo joke when she fired back her response.

"People in covfefe houses shouldn't throw covfefe," she shot back.

You can watch exactly what she said at the conference in the full video below.
