“Absolutely most insulting conversation I have ever had with anyone,” wrote Kelly in the email obtained by BuzzFeed News.

"What an impolite arrogant woman. She immediately began insulting our people accusing them of not following the court order, insulting and abusive behavior towards those covered by the pause, blah blah blah," he added, apparently mocking Warren's concerns.

Kevin Carroll, the department's senior counsel, responded. “Too bad Senate Majority Leader McConnell couldn’t order her to be quiet again!" he said, referring to Senate Majority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellThe Hill's Morning Report: Trump walks back from 'send her back' chants GOP rattled by Trump rally Third Kentucky Democrat announces challenge to McConnell MORE's (R-Ky.) use of Senate rules to silence the senator during a speech, a moment that quickly went viral.
