McConnell interrupted Warren on the grounds that she had impugned another senator.

“Sen. Warren was giving a lengthy speech. She had appeared to violate the rule. She was warned. She was given an explanation. Nevertheless, she persisted.”

Clinton's tweet also included a link to the video of the Massachusetts senator reading King's letter aloud outside of the Senate after she was rebuked.
